This question therefore always remains unanswered, and that is why we are here to find out whether it is safe to drive with a faulty knock sensor or not. Let’s start by thinking about this question: have you noticed that check engine light or knocking noises coming from the engine from time to time? If yes, this could be the major sign of a faulty knock sensor. And this could be the sign of a malfunctioning knock sensor in your vehicle. Now, another question arises: is it safe to drive with a faulty knock sensor? By the way, what causes a knock sensor to malfunction? Well, for that, we need to discover other basic things, which are explained below.
What Causes a Knock Sensor to Deteriorate? The Real Reasons
What causes a knock sensor to malfunction in any car? Why not start by understanding the knock sensor process? The knock sensor is located on the cylinder head, engine block, or intake manifold. The main function of the knock sensor is to detect and sense the vibrations caused by engine knocking. Your vehicle’s PCM will send a command to adjust the ignition timing. This will even prevent an explosion, in case it is about to happen. Then it will identify the valid ping, after which the ignition timing will be retarded to protect the engine from any possible damage.
A knock sensor can even prevent an explosion
What Causes a Knock Sensor to Deteriorate?
There are several reasons why the knock sensor fails. And today, we are going to discuss all those possible reasons that can contribute to it. The first reason could be the Check Engine light coming on. Another symptom could be continuous vibrations, especially at high speed, dull noises coming from the engine, poor acceleration, poor fuel economy, and even misfires.
What causes a bad knock sensor is its mishandling. Perhaps you handle it roughly or have dropped it sometimes. It can even deteriorate if you remove it improperly. The main culprit is sometimes the connectors too. If they are pushed or pulled roughly or are not aligned, the risks of breaking these fragile parts of the sensor increase. Sensors are quite fragile and you need to take care of them to preserve their lifespan for a long time.
An expert check is important when problems are detected
It is always recommended to call in experts if you are handling the sensors for the first time. Also, reading and understanding some good maintenance tips from renowned experts can always help.
What Happens When a Knock Sensor Fails?
Of course, the vehicle is affected in one way or another. So here are some phenomena you might encounter in the car when the knock sensor fails. Here is the answer to what the knock sensor does:
1. Decreased Power
Once your car detects the bad knock sensor, you will see your vehicle losing power. This depends on the octane limit of any engine and how much it will lose due to its power. The power loss stops and even decreases the timing. Overall, the vehicle’s performance is halted. That’s how bad the knock sensor can get for the vehicle.
2. Fuel Consumption Gone
This can even slow down the vehicle’s acceleration, especially on the highway. You might need to apply more pressure on the accelerator to fuel the vehicle. This means your car has lost fuel consumption. In this case, take your vehicle to a mechanic as soon as possible.
3. The Engine Acts Unusually
Another symptom of a bad knock sensor is that the engine will not behave properly. It will be unable to function well especially when you are carrying a very light or very heavy load. Sometimes the light does not come on even after such problems. But if somehow your car is misbehaving, it would be enough to take it to the mechanic.
You need to palpate your engine to confirm the knock sensor malfunction
4. Check Engine Light
The check engine light often illuminates your car’s dashboard in case of knock sensor malfunction. Modern cars are equipped with onboard diagnostic systems that monitor many parts and sensors of the car, including knock sensors. That’s why when you notice the check engine light, it can be a sign to alert you to problems with your knock sensors.
5. Poor Fuel Efficiency
One of the main tasks of knock sensors is to optimize the air-fuel ratio by ensuring proper combustion. Thus, a faulty knock sensor can negatively impact this process. At this time, the ECU cannot make the necessary adjustments, which affects fuel distribution and leads to inefficient fuel consumption by your car.
6. Risk of Knocking and Engine Damage
The knock sensor is essential to prevent engine damage caused by knocking, i.e., the uncontrolled and premature combustion of the air-fuel mixture. If the knock sensor fails, the ECU may not be able to accurately detect knocking and damage your engine.
Watch more about the symptoms of a bad knock sensor:
The causes of a knock sensor malfunction are here for you. Now, you need to keep a constant check on the vehicle. Also, to ensure that whenever any of these symptoms appear, you immediately bring it to the mechanic. After all, an experienced and skilled person can handle this much better than we can. So, read this knock sensor guide, follow the tips, and follow it through to ensure you know what to do in case of a bad knock sensor.
Electric or hybrid: which is best for me
Have you thought about buying a new car? Brand and model have always been the first things that come to mind. Today, we have to make another decision. Should I buy an electric or hybrid car? Here are some points to consider to help you make the right decision.
The UK is considering banning petrol and diesel cars from 2030. With this in mind, it makes sense to plan ahead.
ELECTRIC CARS – ADVANTAGES
The development of electric cars is progressing more and more. Due to their advantages, more and more customers are enthusiastic about electric cars. There are several reasons for this; driving pleasure thanks to powerful acceleration from a complete stop and reduced noise. The main argument for buying an electric car is that it is environmentally friendly. The car becomes a purchase that is both a status symbol and an expression of one’s idealism. Thanks to the electric motor, which does not require combustion, no CO2 or other greenhouse gases are emitted. Even in the overall CO2 balance, which takes into account the entire lifespan of the electric car, it beats conventional combustion engines.
The electric motor is also very energy efficient: the integrated motors have an efficiency of up to 90 percent. This means that 90 percent of the energy input can also be used. This value is only 20 to 40 percent for combustion engines. Furthermore, electric cars do not consume oil in the form of petrol or diesel, thus preserving this resource.
THE DISADVANTAGES
The range of electric cars is still far from comparable to that of diesel and petrol. Electric cars remain more expensive than thermal engines, and recharging the batteries is not always easy. These are facts that still hinder the sale of electric and plug-in hybrid cars in most countries, but they are on the increase.
Most of the disadvantages of electric cars are due to the current state of technology. The most important cost factor remains the vehicle’s battery. The production of lithium-ion batteries, which is being established, is not only costly but also leaves a significant CO2 footprint that weighs on the overall environmental balance of electric cars.
HYBRID CARS – ADVANTAGES
Hybrid cars aim to combine the advantages of combustion engines and electric propulsion. Since an electric motor is already very efficient at low speeds, it is particularly well-suited for starting and low speeds. In contrast, at high speeds, the thermal engine performs better. Most hybrid cars can automatically switch between the two engines or operate both together when it is most efficient.
Thanks to the synthesis of the two types of transmission, fuel consumption and emissions can be reduced, dynamic driving performance created, and a long range achieved for a reasonable additional cost. The electric motor supports or replaces the combustion engine – especially where it is inefficient – and serves in certain situations as a performance booster.
THE DISADVANTAGES
Even before taking a closer look at a hybrid car, one thing that immediately catches the eye is its high price. Many models are now offered in both classic thermal and hybrid versions, and the price difference is often several thousand euros more for the hybrid model. This is partly due to the need to install both electric and combustion technology.
This brings us to the next disadvantage, weight. Precisely because both systems are installed, the hybrid weighs significantly more than a conventional model. The extra weight becomes a problem especially when driving on the motorway, as fuel consumption increases significantly there and can even be higher than that of a combustion model. Two systems also mean that more space is required. The battery has to be stored somewhere, which is usually at the expense of the boot space. The fuel tank is also smaller, so fuel is no longer sufficient for long journeys. From an ecological point of view, a hybrid is only cost-effective if you drive it for a long time and especially on short distances and in city traffic.
ELECTRIC OR HYBRID – WHICH IS THE BEST OPTION?
An electric vehicle requires up to 50% less energy than a hybrid vehicle. Studies show that operating an electric car produces up to 70% less greenhouse gases, nitrogen oxides, and particulates than a hybrid car. So, if you are concerned about emissions, you should invest in an electric vehicle.Top 5 Rated Electric Vehicles in the UK:
Hyundai Ioniq 5 – With high charging speed, numerous assistance systems, and generous interior space, Hyundai is even tackling the electric luxury class.

The advantages and disadvantages of electric cars
For some time now, electric cars have been presented as the solution to the automotive industry’s greenhouse gas problems, with the potential to reduce our dependence on fossil fuels and reduce CO2 emissions on the roads. However, the transition to electric vehicles (EVs) has been slow, and many people are wondering if the benefits of these cars truly outweigh the costs. For people considering buying an electric vehicle, our recommendation would be to explore your options and examine the advantages and disadvantages individually, as they could also be affected by your driving environment, habits, and preferences.
HOW DO ELECTRIC VEHICLES WORK?
Instead of an internal combustion engine, fully electric models use an electric motor powered by a rechargeable battery. The motor generates less noise and allows the car to operate without emitting harmful exhaust gases. The battery stores electricity, an inverter converts the direct current (DC) from the battery into alternating current (AC) which is supplied to the traction motor. These vehicles have a unique transmission system that transfers power to the wheels. To charge the battery, the EV must be plugged into a charging station or a wall outlet.
THE ADVANTAGES OF ELECTRIC CARS
+No Fuel This allows people to significantly reduce their operating costs, as electricity is generally much cheaper than gasoline and diesel. However, this will also depend on the local charging infrastructure and charging rates. Some models can even be charged at home on a standard outlet. By using electric vehicles, we can become less dependent on fossil fuels and the volatile fuel market. Car batteries can potentially be charged using 100% renewable energy sources.
+Zero Emissions The obvious advantage of switching to all-electric is that the cars do not release harmful gases into the atmosphere. In this sense, they are even more environmentally friendly than hybrid electric vehicles which still use internal combustion engines. Features such as regenerative braking also reduce the amount of energy wasted.
+Low Maintenance Electrically powered units are generally much easier to maintain than conventional combustion engines. They have fewer moving parts, meaning there are fewer parts to replace. There are no valves that can clog or seals that need to be replaced regularly, and you won’t have to worry about changing the engine oil.
+Tax Benefits Some governments offer tax benefits and financial incentives for low-emission vehicles. One of the advantages of owning an electric car is that you might be able to avoid certain environmental costs, such as urban tolls.
+Smooth Driving Thanks to the electric motor, noise pollution is significantly reduced, contributing to a better driving environment. The simple transmission system virtually eliminates stalling and allows the vehicle to operate with just the accelerator pedal, steering wheel, and brake pedal. After many technological developments, these models are lighter and capable of accelerating with surprising speed. For example, the Tesla S model is capable of accelerating from 0 to 60 miles per hour in just 2.5 seconds.
THE DISADVANTAGES OF ELECTRIC CARS
–High Investment Costs Electric vehicles are certainly not cheap, and many people do not have the capital to buy a new one. Used vehicles are obviously cheaper, but the vehicles still have a higher average resale value than standard gasoline vehicles. Hopefully, the market segment will see a reduction in prices as technology advances and more of them are sold. On the other hand, in the long term, fuel savings could offset the money invested.
–Electrical Infrastructure Issues Although more and more people have made the switch and companies and governments have started investing more in the electrical infrastructure for these vehicles, the number of charging stations in different locations remains quite limited. For long-distance trips, car owners will need to ensure there are enough charging points along the route. Another issue is that the time needed to charge the vehicle varies depending on the charging method and the battery’s condition.
–Driving Limitations Electric vehicles have limited range and speed. On average, most models have a range of about 50 to 100 miles on a single charge. However, newer high-end models have much higher ranges. For example, the Chevrolet Bolt has a maximum range of 238 miles.
–Expensive Batteries Although battery packs generally last a long time, they eventually wear out. A replacement can cost thousands of euros.
–Silence The fact that traction motors are so quiet is not always an advantage. For example, sound can be important to warn other road users and pedestrians when a car is coming around the corner or leaving.
HOW DOES TEMPERATURE AFFECT VEHICLE RANGE?
Range can be affected by extreme temperatures (hot or cold). Data has shown that the optimal operating temperature for electrical systems is around 21.5 degrees Celsius. An important factor is the efficiency of the heating and cooling systems. Car manufacturers have attempted to develop solid thermal management to avoid performance losses.
ARE ELECTRIC CARS REALLY BETTER FOR THE ENVIRONMENT?
Reductions in annual emissions are evident, but the sustainability of these cars is still widely debated. For example, production processes are still carbon-intensive, and most of them still rely on grid electricity, which is often produced from non-renewable energy sources. The lithium-ion battery recycling industry is also underdeveloped and ill-prepared for the increasing waste management requirements.
Car brake lights do not turn off – Possible reasons
Brake lights use a switch to indicate whether the lights are on or off. This brake light switch is connected to the brake pedal. It completes the circuit when you press the brake. Sometimes, brake lights do not turn off due to a circuit error or other reasons.
The reasons can range from a circuit failure to a malfunctioning brake pedal. There is a piston-style button that completes the circuit. Pressing the brake switch causes the circuit to open and the lights to turn on.
Learn more about the topic below.
How Do Car Brake Lights Work?
Your braking system, which includes your brake lights, consists of the brake pedal, the striker, the brake light switch, the lights, fuses, and wiring. When you press the brake pedal, it makes contact with the associated brake light switch, allowing the brake lights to illuminate.
The electrical components use this switch to alert your brake lights when the pedal is depressed. When you release the brake pedal, the striker disengages the brake light switch, which turns off the brake lights.
While this is a simple explanation of how brake lights work, damage to the striker or the brake light switch can lead to brake light issues.
Why Don’t Car Brake Lights Turn Off After Turning Off the Ignition?
It is necessary to diagnose the brake switch or pedal issue to fix it properly. You can check the brake pedal rod to find the switch. Or entrusting the car to an expert mechanic would also be a wise decision.
Pressing and depressing the brake pedal several times can help connect the switch and the tail lights. There is a rubber plug that pushes the piston-style button. You may need to replace the rubber plug if it is not functioning correctly.
Here are the reasons why brake lights do not turn off even when the car is off.
The Brake Switch Is Not Working
Brake lights do not turn off if the switch is stuck or not working properly. You may need to adjust or replace the brake switch to resolve the issue.
The automobile’s battery begins to drain if the brake lights remain on for a long time. Professionals suggest disconnecting the car battery when facing this problem. Make sure to save the battery’s energy to start the car until the issue is resolved.

According to expert maintenance advice, a stuck brake switch is the most common reason why the lights stay on. You can replace the brake pedal switch to identify the problem.
Diagnosing the brake switch would help discover the main issue. Opt for replacement if the brake switch is faulty.
Stuck Brake Pedal
A stuck brake pedal can be another reason why the brake lights remain on. Brake lights will not turn off if the brake pedal does not properly disengage the switch.
The lights stay on until the connection between the switch and the pedal is active. The rubber plug also has a lot of work to do in this process. It helps to adjust the brake pedal appropriately.
Debris or corrosion between the switch and the pedal can also affect the process. Consulting experts would be great to solve the problem in no time.
Make sure to have your car repaired and maintained by a professional if the problem does not resolve.

Brake Light Switch or Sensor Failure
This is the most obvious cause of your brake lights malfunctioning. When the switch inside the braking system fails, your lights do not turn off. The switches and sensors in a braking system indicate to the lights whether the pedal is up or down.
If one of them is broken, the lights will receive a wrong message. The brake pedal switch is placed near your brake pedal and can be adjusted frequently.
Faulty Brake Pedal Spring
The brake pedal has a spring that allows it to return to its initial position once you release it. This spring could weaken as it ages.
With the pedal not returning to its normal position, the brake lights stay on. Furthermore, your brake pads might remain engaged, leading to increased wear on the pads and rotor.
Electrical System Malfunction
A problem in the electrical system can affect various components, including the brake lights. These faults can cause the lights to stay on, not turn on, or only work intermittently.
This might be the most difficult problem to solve and should not be considered until all other possibilities have been exhausted.
Incorrect Bulbs Installed
This is rare, but it can happen if you have just updated your tail lights or brake lights. There are two types of bulbs, each with one or two circuits.
Installing a single-circuit bulb in a dual-circuit socket can short-circuit the system and cause the brake lights to stay on.

How to Fix Car Brake Lights That Don’t Turn Off
Check Your Previous Projects
If you have just installed an aftermarket system that requires removing or replacing the tail light assembly, you should go back and recheck your work.
If you have modified any of the wiring, check that it is properly connected according to the aftermarket manufacturer’s instructions.
Check Brake Wiring
Examine the wiring under the tail light and under the dashboard, near the brake light switch. Even if the wire and insulation appear to be in good condition, you might have a wiring issue.
It is also a good idea to check the fuses under the hood and in the cabin. If a fuse is blown, the brake light switch may not function correctly.
You can also consult the manufacturer’s maintenance manual to see which grounds the braking system uses. Check that the grounds are clean, secure, and in working order.
Test a Brake Light Switch
A brake light switch is a very basic mechanism that you can most likely test yourself with a multimeter.
When you press the switch, the circuit should be open, and there should be no continuity. This turns off the brake lights. When the switch is released, there should be no interruption. This activates the brake lights.
After confirming continuity, ensure that the resistance transferred via the switch is correct.
A faulty switch might pass a continuity test but not be able to transmit enough electricity to activate the brake lights. The exact switch specifications should be specified in the OEM maintenance manual.
The wiring diagram is helpful when checking the brake light switch connector. It will tell you which pins to connect to illuminate your brake lights. The manual may offer additional diagnostic advice and information on the system’s expected behavior.

How to Check Brake Light Functionality Properly
There are several techniques to test brake light functionality. Although you might prefer to rely on your sophisticated dashboard to do the job for you, nothing beats experiencing the brake light behavior yourself. Here are some simple methods:
Ask for Help
To test your brake lights, simply ask a friend, family member, neighbor, or passenger to press the brake pedal while you watch or to check the lights while you operate the pedal.
Reflection in a Store Window
When you are not at home, look for a commercial area with parking right in front of a store. The store window can be used as a mirror. Back your automobile into a parking space in front of a store window if traffic and pedestrian flow allow.
Now, check your rearview mirror and apply the brakes. If everything is in order, all brake lights should illuminate. You should also check your rear turn signals and hazard lights.
Repeat with the engine off and the ignition turned off. Note any lights that do not function for later measures. The turn signals will not work if the ignition is off.
Try It with a Garage Door
If you are at home, park your car in the garage and lock the door behind you. If your brake lights reflect on the garage door when you press the brake pedal in a dark garage, you will be able to see through your rearview mirror or side mirrors.
This strategy can also be used in a covered parking lot away from home. Simply back into your parking space and check in your rearview mirror for brake light activation while applying the brakes.
This is also an excellent technique for testing other lighting issues, such as when your tail lights do not turn on.

DIY Tools
If you are at home and do not have access to a garage or assistance, you can build a tool to push and hold down the brake pedal. Here’s how to create one:
Open the driver’s side door. Press the brake pedal about one inch with your left hand. Measure the distance from the pedal to the front of the driver’s seat. Depending on the seat position, it will be between 18 and 22 inches.
To achieve this length, cut a 1″ x 2″ finishing board or an old broom handle.
With this tool, press the pedal and wedge the rear end of the tool against the driver’s seat. The brake lights will now be available for you to inspect. Surprisingly, a basic snow brush is about the right length for this purpose.
Final Thoughts
Your automobile’s brake pedals may require special treatment to stay in good condition. If the brake lights do not turn off even when the ignition is off, make sure to check the brakes as soon as possible.
Why Your Car Hesitates When Accelerating from a Stop
Car hesitates when accelerating from a stop or when going uphill is really frustrating, and it can be dangerous in certain situations like highway entry and exit, where acceleration may be needed to merge into traffic. This usually happens because your engine is not generating enough power to facilitate the speed increase, but the exact culprit may require time and knowledge to identify.
This article includes a comprehensive list of 11 common reasons why the car hesitates during acceleration. Go through each one to rule out the true culprit one by one and immediately perform the required replacement or maintenance to enjoy smooth and safe driving.
Car hesitates when accelerating after a stop: 11 Common Reasons
Essentially, engine lag or hesitation during acceleration occurs when the engine doesn’t receive enough power, and it needs more power to accelerate from a dead stop than to maintain the speed of a moving vehicle.
The engine generates power by creating combustions in its chamber. The input for such combustions, or explosions, is a mixture of air and fuel in a fixed optimal ratio, which is ignited by the spark plug. The engine houses several cylinders, and combustions take place in these cylinders in a continuous order so that a continuous supply of energy is generated to run the engine.
Therefore, if there is a problem with any of the engine components that control such a mechanism for igniting the fuel and air supply, the engine will not get enough power when needed, causing the car to hesitate when accelerating from a stop.
The reasons for this problem can be quite lengthy. Inspect the following components in turn when you encounter the problem of the car being slow to accelerate after stopping:
1. Air Filter

One of the most common reasons that make your car hesitate when accelerating from a stop, and the simplest to fix, is a dirty air filter. Your engine needs a constant supply of air to operate, and the air part of this equation can be significantly affected if the air filter is dirty and clogged with dust buildup.
A clogged air filter means the engine will not receive enough air to produce optimal combustion, thus generating less power than what is needed to accelerate the car. If it persists, this small problem will choke the engine, negatively affect fuel economy as well as your driving experience and safety. Fortunately, if it’s the culprit, you just need to remove the air filter from the airbox, inspect it, and replace it with a new one.
2. Mass Air Flow Sensor
This is the next component to inspect after ruling out the air filter.
The Mass Air Flow sensor keeps track of the volume of air entering the engine and relays the information to the ECU (Engine Control Unit). The computer uses this information to decide the corresponding amount of fuel that the fuel injectors need to deliver.
A faulty or clogged sensor transmits incorrect information, so the engine does not receive the correct amount of fuel it needs, leading to suboptimal power generation and thus causing the car to hesitate when accelerating from a stop or when going uphill. Note that if the Mass Air Flow sensor is the cause, it may or may not trigger a fault code.
3. Fuel Pump
While your engine needs air and fuel to be injected into the combustion chamber, the fuel is stored in the fuel tank.
Therefore, a fuel pump, also called a “fuel transfer pump,” is needed to transfer gasoline or diesel from the fuel tank to the engine, more precisely to the carburetors or fuel injectors, depending on the type of vehicle you own. The carburetors or fuel injectors then disperse the fuel into the engine’s combustion chambers.

It goes without saying that when your vehicle’s fuel pump malfunctions, the engine will not get the right amount of fuel at the right time, so its performance will be impaired.
A dirty or damaged fuel pump can trigger a handful of problems. A clogged or faulty fuel pump means the engine does not receive enough fuel at a given time to generate sufficient power, causing the car to hesitate when accelerating from a stop.
4. Fuel Injectors
As mentioned above, once the fuel pump transfers the fuel from the fuel tank to the engine, the fuel injectors then spray the fuel into the cylinder. The fuel is then mixed with air in a certain proportion and then ignited by a spark plug to create combustion.
Like the air filter and fuel pump, the fuel injector is also prone to accumulating dirt and sludge over time, affecting its ability to deliver the correct amount of fuel for combustion. As a result, the engine fails to produce enough power to take off smoothly after a complete stop.

5. Fuel Filter
Similar to the air filter, the fuel filter tends to get dirty or clogged. This problem can lead to power loss or even failure to start, as the engine does not receive enough fuel at a given time for optimal performance, thus causing your car to hesitate when accelerating from a stop or when the vehicle is going up a slope. Of course, suboptimal engine performance will also result in poor fuel economy.

The fuel filter is located in the fuel tank on most recent vehicles and will require a visit to the workshop for inspection if you are not used to handling it. If your vehicle has an external fuel filter, it is simple and inexpensive to replace.
6. Accelerator Pump
If you drive an old vehicle equipped with a carburetor, it must be fitted with an accelerator pump. The delay may be due to pump wear or the need for repair. It is a piston rod with a rubber-sealed piston that injects a small amount of raw gas into the carburetor. The influx of fuel and air makes the engine more responsive to acceleration.
When the rubber seal is worn, it sends a large volume of air with little or no gas to the plunger cylinder. As a result, the car hesitates when accelerating from a stop. You need to replace the pump as well as clean or replace the fuel filter to fix the problem.
7. Throttle Position Sensor
The Throttle Position Sensor is a component of your car’s throttle body system. It is located between the engine intake manifold and the air filter.

The job of the Throttle Position Sensor is to ensure that the engine receives the right amount of air and fuel for optimal combustions.
Whenever you press the accelerator pedal, the throttle valve rotates to let a precise amount of air into the combustion chamber through the engine intake manifold. The more you press the pedal, the more the valve opens.
At the same time, the Throttle Position Sensor sends signals to the engine control unit to report the position of the throttle valve. Simultaneously, the ECU uses this information to adjust the amount of fuel to be instilled into the chamber at a given time, thus creating the ideal conditions for combustion to take place.
It is quite common for the Throttle Position Sensor to malfunction, as it consists of mechanical parts that can wear out and need replacement. A faulty Throttle Position Sensor will transmit incorrect data to your car’s computer.
A faulty sensor will not send the correct information, which will deprive the engine of enough fuel and air it needs to operate properly during acceleration.
There are other signs you can look for to better ensure that a faulty Throttle Position Sensor is actually the culprit. In most situations, when there is a problem with the Throttle Position Sensor, the Check Engine light comes on. Furthermore, most car manufacturers offer a “limp” mode with reduced power in case of engine failure. This is designed to allow a driver to exit a busy highway more safely.
If a faulty Throttle Position Sensor is indeed the culprit causing your car to hesitate when accelerating from a stop, you should have it inspected immediately. When your engine does not receive the correct air-fuel ratio for proper operation, it runs below its optimal efficiency. The result is inevitably lower fuel economy and will damage your engine, thus reducing its lifespan.
8. Exhaust Gas Recirculation (EGR) Valve
The role of the EGR valve is to recirculate the exhaust gases generated during engine combustion back into the combustion cycle to be reburned, thus reducing engine temperature and reducing the production of toxic nitrogen oxide.
EGR valves open and close to control the gas flow. Over time, the exhaust forms a hard, thick carbon wall, blocking the EGR valve open or closed. This will block the system’s passages and result in incorrect data being sent to the engine computer, leading to an incorrect amount of air and fuel being injected into the engine chamber, thus causing delayed acceleration.
A stuck or faulty EGR valve also increases emissions as well as engine temperature, and a heated engine will never operate optimally or last very long. This problem can, over time, reduce your car’s mileage and shorten the engine’s lifespan. This is why car manufacturers recommend cleaning the EGR valve and passages every 50,000 miles or less.
Starting from the year 2000, engines in newer vehicles are equipped with a more advanced ignition coil pack that sits directly on top of the spark plug of each engine cylinder to directly ignite the plug. These coil packs are electronically controlled by the car’s engine computer. Coil packs generally create a hotter and stronger spark, which in turn produces better combustion and better power in a car’s engine, compared to the older ignition mechanism that required an ignition coil, a mechanical distributor, and spark plug wires.
Needless to say, when a coil pack starts to fail, it will affect the ignition of the spark plugs, thus preventing ignition and combustion. Therefore, the engine will not generate enough power, causing your car to stall when accelerating from a stop, under hard operating conditions, or when the engine stumbles and surges. Fortunately, coil packs are easy to access and replace, usually requiring nothing more than a screwdriver or a small socket wrench.
10. Oxygen Sensor
The job of the oxygen sensors or O2 sensors is to monitor the oxygen content of the exhaust gases relative to other gases and send this data to the engine control unit for emission control and fuel metering decisions. This component is located in the exhaust stream, usually one closer to the exhaust manifold and one further down the exhaust pipe.
In other words, oxygen sensor data contributes to precise engine timing, combustion intervals, and the correct air/fuel ratio
The arguments for and against removing the catalytic converter
People’s choice to remove the catalytic converter is based on the fact that it reduces engine power. There are arguments for and against.
Removing the Catalytic Converter: Why Do People Want to Do It?
The catalytic converter has been used in automobiles since the 1970s. Its role is to reduce the amount of harmful gases a vehicle emits into the environment.
The converter reduces the harmful effects of gases by releasing a kind of chemical catalyst.
Proponents of its removal believe that it creates too much backpressure on the exhaust system and affects the vehicle’s performance by preventing it from operating at its optimal power.
Another reason is a clogged or failing converter, as replacing it with a new one is an expensive solution.
Most people choose to replace it with something energy-efficient but cheaper, and others prefer to get rid of it completely. However, performance improvement is the main reason for removing the catalytic converter.
The basic principle is that the engine can draw in more fresh air if it is possible to release a larger amount of exhaust gases in a short period.
More air in the engine means it can burn fuel more efficiently, allowing more power to be directed to the vehicle’s operation.

Converter Removal or Straight Piping
The converter is removed as part of the process called straight piping. This creates a straighter path for exhaust gas evacuation.
Along with the converter, this involves the removal of resonators and mufflers. This creates an exhaust system that has no obstruction to the release of exhaust fumes.
The car’s power depends on the degree of restriction of the removed converter. It will also depend on whether you opt for a high-flow replacement racing catalytic converter.
However, you must not remove any part of the original emission system. Furthermore, instead of discarding the converter, you can improve performance by installing a wider exhaust pipe and less restrictive mufflers.
Problems with Removing the Catalytic Converter
Without a catalytic converter, you can increase engine performance. But it causes so many other problems that you will wonder if it’s a good idea to go through all that trouble just for a bit of extra power.
Polluting the Environment
The converter reduces the harmful effects of exhaust fumes. Some of them can even reduce harmful elements by 90%.
Without this component, your car will release toxic fumes directly into the atmosphere and cause more pollution than it should.

Breaking the Law
Removing the catalytic converter without replacing it with a new one or any other alternative is illegal.
Laws and regulations regarding automobile emissions and air quality require that a car emit within a certain limit. However, the limit depends on the state and city you live in.
Your car’s emissions must comply with the emission standards of your area. Seizure and scrapping of the car could be the consequence of violating emission laws.
However, unlike the UK, there is no MOT test (annual vehicle test for technical inspection, safety, and emissions) in the United States.
A car is considered roadworthy as long as it has functional front and rear lights and can accelerate above 55 mph.
But the car must pass an emissions test every two years (not in all cities, however).
Annoying Sound
Completely discarding the converter also leads to noise pollution. Without this component, there would be no muffler to suppress the engine noise.
Therefore, the sound will be quite loud whenever you rev the engine.
More Fuel Expenses
It’s exciting to find a way to increase your vehicle’s acceleration. But remember that it won’t save you fuel. Removing the component means consuming more oil and increasing your car expenses every month.

How to Remove the Catalytic Converter?
If you are still ready to take risks for a few notches on the performance indicator, follow the procedure for removing the catalytic converter from the exhaust system below!
Disconnect the O2 Sensor: The first step is to disconnect the O2 sensor. You can do this with a special tool called an O2 wrench.
Removing the Converter: The next step is to separate the converter from the exhaust system. You need to unscrew it and slide the exhaust pipe. If it is welded to the system, cut it with a rotary saw.
Getting Rid of the Converter: It is possible to scrap the converter in pieces and resell it to a junkyard. However, the converter core contains precious metal. You can sell it for a good price if you manage to separate it from the core.
Can Your Car Run Without a Catalytic Converter?
Technically, nothing prevents you from driving a car without a catalytic converter. Even though there will be additional noises and performance issues, your car will still run.
On the other hand, driving without a catalytic converter is illegal, so it’s not always a good idea.
All states require your car to be equipped with a catalytic converter to reduce air pollution. Driving without it probably won’t harm the car, but it will harm the environment more.
You shouldn’t drive for long periods without this system for that reason alone. The best solution is to have it replaced immediately!
FAQ on Catalytic Converter Removal
What does a car without a catalytic converter sound like?
If you own a car without a catalytic converter, you will hear a loud rumble or roar when you start the engine.
When you press the accelerator, this sound becomes louder. Because the exhaust is not working properly, the car runs more roughly than usual, often stuttering when you shift gears.
Will removing the catalytic converter damage the engine?
No, removing the catalytic converter will not damage the engine. The role of the catalytic converter is to clean the exhaust gases produced by the engine.
Most modern automobiles will not run properly if the catalytic converter is removed. As mentioned earlier, without the cat, the oxygen sensors installed before and after the cat will not be able to function within range.
This will lead to the generation of engine error codes, which will have a detrimental influence on engine performance. Although removing the catalytic converter does not damage the engine, you should expect a decrease in engine power and fuel economy.
Watch this video from Car PROblems to learn more about all the pros and cons of removing a catalytic converter!
Yes, driving without a catalytic converter is prohibited in most US states. However, the Environmental Protection Agency (EPA) has created several provisions allowing driving without a CAT.
Although legislation varies by state, it is advisable to be cautious and always keep a functioning catalytic converter in your car.
The Clean Air Act of 1970 requires all automobiles to be factory-equipped with catalytic converters compatible with carburetors.
Most automobiles built before 1970 (the year the Clean Air Act was enacted) were not factory-equipped with catalytic converters as standard.
As a result, some jurisdictions (like Georgia) will allow you to pass emissions tests if your car is over 25 years old.
How long can I go without replacing a catalytic converter?
Although they are supposed to last at least 10 years, catalytic converters do not necessarily need to be replaced after that period.
It should only be changed if service specialists advise it and whenever you start to notice these problems.
Does removing the catalytic converter increase fuel consumption?
The catalytic converter circulates exhaust gases and engine air through tiny channels. Its removal allows the engine to breathe more freely and produce greater power.
Depending on the type of vehicle, the sound is also improved, and fuel consumption can be reduced by up to 10%.
How much does it cost to remove the catalytic converter?
You should budget between $300 and $1,650 (excluding labor) for removing the catalytic converter for the majority of current vehicles.
However, parts costs and local labor rates generally affect these prices. For example, the cost of replacing a typical catalytic converter in a contemporary vehicle can range between $500 and $2,200!
Best Oil for High Mileage Engines
In the market, there are many types of engine oil with specialized characteristics suited to each car’s condition. Choosing the right engine oil will help reduce engine wear and ensure the car’s proper operation. If your car has traveled 75,000 miles or more, it’s time for you to find specialized oil brands for high-mileage vehicles instead of using ordinary oil. So, what is the best oil for high-mileage engines and what are they? Let’s follow this topic to learn more:
What is High Mileage Oil?
What is the difference between high mileage and regular oil? (Photo: pinterest.com)
What should be considered as high mileage oil? If you search online for high mileage oils, you get thousands of results, but the problem is that there is no definitive idea on this matter. This oil is made with special base oils and anti-wear additives to minimize oil leaks and is formulated to protect car engines with over 75,000 miles and vehicles with longer oil change intervals.
Gradually, O-rings, gaskets, and seals, among other components, begin to deteriorate as the engine ages. They become less capable of performing their many tasks, including keeping the oil sealed inside the engine. That’s why we need a special oil for these situations. High mileage oil can alleviate common problems in older engines, such as worn gaskets and seals, high oil consumption, or oil pressure. So, what benefits can this type of oil bring:
The ingredients in high mileage oil contain seal conditioners whose main role is to soften and rejuvenate the engine seals, which can partly prevent oil leaks and seal deterioration.
The additives in this oil can enhance protection to limit engine wear. Furthermore, it also minimizes engine damage and reduces friction between metal parts.
Compared to regular engine oil, high mileage oils can improve detergency as they contain additives that will keep your engine clean by reducing deposit buildup in the engine compartment.
When to Use High Mileage Oil – Answer
Your concern: what is the best time to switch to high mileage oils? As we mentioned above, when your car reaches about 120,000 kilometers or more, it is recommended to consider using high mileage oils. However, the exact number sometimes depends on the engine’s condition and the specific model, so be sure to ask your mechanic or the manufacturer before changing the oil type.
Another symptom is when you notice your engine is consuming more oil than normal and you will constantly need to refill the oil tank. This sign indicates that your car needs to switch to another type of car oil suitable for the car’s engine or needs to be checked to see if your car’s engine has problems.
Moreover, strange noises from the car engine are also one of the symptoms prompting you to use high mileage oil. Over time, regular oil is no longer able to lubricate your engine parts, causing them to rub against each other during operation, consequently, you will hear a loud noise or even wear and damage. Therefore, when they hear strange noises from the engine, car owners should have their car checked immediately and consider using high mileage oil if necessary.

High-pitched car noise while driving
When a car is running, the engine operates at high speed. This means many parts are moving, and a high-pitched squeal from the car while moving can occur when something is out of place.
We have years of experience solving these issues and explain them in more detail below.
High-Pitched Squeal from the Car While Moving: What Could It Be?
When you hear a high-pitched squeal coming from your car while it’s moving, it’s natural to worry and wonder if there’s a serious problem. Although there could be underlying issues, sometimes it’s a relatively simple problem to fix.
It’s worth noting that many potential causes of this noise are related to the car’s belts and pulleys. When these components malfunction, your car’s performance can be affected, and this annoying high-pitched squeal can disrupt your driving experience.
Some of the most common reasons for this noise while driving include a worn fan belt (serpentine belt), a faulty alternator pulley, a slipping idler pulley, misaligned suspension, a defective V-belt, or worn wheel bearings.
Worn Fan Belt (Serpentine Belt)
One of the most frequent culprits behind a high-pitched squeal from a car while moving is a worn fan belt, also known as the serpentine belt. When this belt deteriorates, it can cause several car problems.
The serpentine belt plays a crucial role in power steering, so if it’s not working correctly, steering becomes more difficult. It’s essential to address this issue quickly, making it a good starting point for inspections.

The belt may show signs of wear, such as cracks or misalignment. Additionally, some vehicles are equipped with both a timing belt or timing chain, which can also cause similar issues. Faulty belt pulleys can also contribute to these problems.
Faulty Alternator Pulley
A faulty alternator pulley is another potential source of a high-pitched squeal while driving. This pulley contains bearings that can wear out, producing the distinct noise you hear.
When the alternator pulley fails, it needs to be realigned or replaced entirely to ensure the belt functions properly. This issue typically has a minimal impact on the vehicle’s performance.
Slipping Idler Pulley
Another concern related to the high-pitched noise is a slipping idler pulley. The idler pulley is an engine component that provides tension and guides the engine drive belt, ensuring the proper operation of power steering and the water pump.
When this pulley slips, it can wobble and create the loud noise you’ve noticed. Driving with a slipping, erratic pulley is uncomfortable and should be addressed promptly.
Misaligned Suspension
Misaligned suspension can also be responsible for the high-pitched squeal from the car while moving. This misalignment can result from damage to the suspension system or excessive wear.
Typically, worn springs or shock absorbers can lead to misalignment. As a result, the system loses lubrication, causing loud, high-pitched squeals during movement.

Defective V-Belt
The V-belt contributes to the tension of the drive system, and when it becomes defective or misaligned, it can produce a high-pitched squeal. Misalignment of this belt is a common but relatively easy issue to fix. Regular checks can help detect any tension-related problems.
Worn Wheel Bearings
Faulty wheel bearings can also be the cause of high-pitched squeals. This is a common issue on many cars and can be resolved by replacing the wheel bearing or even the wheels themselves.
The noise may vary depending on the vehicle’s speed, sometimes making it difficult to identify the potential cause. Nevertheless, properly functioning wheel bearings are crucial for long trips, such as road trips, and are essential for the vehicle’s durability.
It’s worth noting that other areas of the vehicle, like the alternator pulley, may also use bearings, and similar noises can occur if any of these bearings near the pulleys or belts are worn or damaged.
Worn Brake Pads
Worn brake pads lead to reduced braking performance, vibrations, and potential damage to the rotor.
The high-pitched squeal from the car while moving is a warning sign of worn pads, and ignoring this issue can compromise your safety, increase stopping distances, and overheat your brakes. Regular inspection and replacement of brake pads are essential for safe driving.

How to Deal with a High-Pitched Squeal from a Car While Moving
Fixing a high-pitched squeal in your car can be challenging due to the various potential causes. Here are some tips to help you address the issue effectively.
Identify the Problem
The first step is to diagnose the problem and identify the source of the high-pitched squeal. Different situations, such as the noise occurring during startup or acceleration, can suggest different causes.
To start, listen carefully while driving to determine the general area of the sound. Once you’ve done that, park your car safely and inspect under the hood.
Replace the Serpentine Belt
In many cases, a worn serpentine belt is the cause of the squealing. Replacing it is often the most common solution.
The serpentine belt is typically held in place by a retaining belt, and most modern cars use a single belt, simplifying the removal and replacement process.
Lubricate the Belts
Applying additional lubrication to the belts and pulleys, including the alternator pulley, idler pulley, and V-belt, can help resolve the issue. Checking the belt tension, if possible, can also help identify the problem.
However, belt tension adjustments may require specialized knowledge, which brings us to our next recommendation.
Seek Professional Assistance
For more complex or serious issues, it’s advisable to consult a professional mechanic with the necessary expertise and tools. Professional help often proves cost-effective and allows for quicker diagnosis and resolution of the high-pitched squeal.

Is It Safe to Drive a Car Emitting a High-Pitched Squeal?
It is not safe to drive a car that produces a high-pitched squeal while driving. The source of the squeal can vary and may come from the engine or another vehicle component. The uncertainty of the problem is concerning.
Although some cars may emit this noise briefly at startup, a persistent squeal after the engine warms up can signal problems with the serpentine belt, alternator pulley, or idler pulley, as mentioned earlier.
Attempting to drive under such conditions is risky, as it may become difficult to control the vehicle, especially if the squealing affects components related to the power steering pump.
FAQ on High-Pitched Squeals from the Car While Moving
Is the high-pitched squeal a serious problem?
The severity of the problem depends on the underlying cause. If it’s related to the brakes, driving with worn brake pads or rotors can be dangerous, so it should be addressed promptly.
A loose or damaged serpentine belt can lead to engine problems, so it’s best to repair it to avoid further damage.
Can I temporarily stop the squealing?
In the case of brake-related squealing, you might temporarily hear a reduction in noise by applying brake lubricant or anti-squeal paste to the back of the brake pads.
However, this is not a permanent solution, and you should still have the brakes inspected and repaired by a professional.
Watch this video by ChrisFix to learn more about how to determine where the squealing is coming from and how to fix a squealing belt!
What is the cost of repairing a high-pitched squealing problem?
The cost of repairs can vary significantly depending on the cause and extent of the problem.
Replacing brake pads or resurfacing rotors can cost a few hundred dollars, while fixing a serpentine belt issue may cost between $100 and $200 or more. It’s best to get a professional estimate for your specific situation.
Can weather conditions affect the squealing noise?
Extreme weather conditions, such as rain or cold, can temporarily affect brake performance and noise. However, if the squealing persists under normal weather conditions, it’s likely due to an underlying issue that requires attention.
Remember, it’s essential to address any unusual or persistent noise in your car promptly to ensure your safety and your vehicle’s longevity, including the rare high-pitched squeal from the car while moving. Always consult a professional mechanic for proper diagnosis and repairs!
How to Increase Power
The need for speed is something that obsesses countless car owners and enthusiasts. Even those who own already fast cars try to extract maximum performance from them. From mild to wild, there are various ways to add extra power to your vehicle. Learn over 20 methods to increase horsepower, including highly effective but expensive methods as well as simple and affordable solutions.
Fun Fact: The Origin of “Horsepower”
Horsepower is a measure of how quickly work is done. Where does the term horsepower come from? Exactly what the word suggests: horses, and a man named James Watt, who used to observe mill horses walking in circles all day, powering the mills.
The origin of the term dates back to James Watt’s invention of a steam engine, which he believed would be at least 200 times more powerful than the horse mill, but he found it difficult to explain to millers the power of the steam engine compared to their horses. So he developed a formula to measure the workload, based on the estimate that a mill horse would pull/push the mill shafts in a 24-foot circle with a force of 180 pounds 144 times in an hour.
He then performed further calculations to prove that such a workload meant a mill horse could push 32,572 pounds (rounded to 33,000 pounds) a horizontal distance of one foot in one minute. This equals one horsepower.
Horsepower thus measures the power a horse gives in pulling, or more precisely, the power required to lift 550 pounds in one second a vertical distance of one foot, or the power needed to move 33,000 pounds in one minute a horizontal distance of one foot.
Factors to Consider When Trying to Increase Horsepower
A major concern for many car owners is how aftermarket modifications affect a vehicle’s warranty. It’s always best to discuss with your dealer how installing aftermarket parts might affect your warranty.
Indeed, car manufacturers are not thrilled about owners trying to rethink their vehicles, which cost a lot of time, money, and brainpower to optimize for aesthetics, performance, and safety. In some cases, certain car manufacturers allow the installation of in-house performance parts when installed by an authorized dealer.
Another aspect you need to consider before tuning your car with aftermarket performance parts is emissions regulations. Many countries and states, like California in the U.S., require certain aftermarket performance parts to comply with emissions standards for the vehicle in question to be considered road-legal.
Even if you choose to install non-compliant parts, it might compromise your ability to pass emissions tests. Therefore, you should take the time to check your local emissions laws before deciding on certain engine performance parts.
Finally, you need to be aware that your vehicle, as it left the factory, was already optimized as a whole, and any modification to one part can make other components less effective. While modifications like an exhaust or intake might have a minimal impact on overall performance and vehicle safety, more significant modifications like a supercharger can considerably alter fuel economy or the vehicle’s long-term reliability.
Therefore, consider all the trade-offs you might be making when making modifications for better power. Also, be prepared that when you opt for a drastic upgrade like a supercharger, you’ll likely need to spend a lot of money upgrading many other parts as well in a complete kit form so as not to sacrifice your car’s overall efficiency, handling, and safety.
How to Increase Horsepower: Effective but Expensive Methods
We’ll start our list of over 15 methods on how to increase horsepower with the most effective upgrades offering immediate and noticeable power gains.
If your vehicle’s engine is naturally aspirated, forced induction will lead to a considerable power increase. Forced induction is one of the most effective ways to increase horsepower. Forced induction can take the form of a turbocharger or a supercharger. These enhancements are popular with hardcore performance enthusiasts and street racers, and you might have seen one in one of the Fast and Furious movies.
This is one of the most expensive engine enhancement modifications, so feel free to skip it if you’re on a budget. But if you can afford it, go for this mod blindly, as a good supercharger will increase your horsepower by up to 625+ and your torque by up to 525+ lb-ft. Such numbers are surely staggering given you’re only benefiting from one set of upgrades.
Before determining if this mod is worth it, you need to understand the basics of superchargers and turbochargers.
To help the engine generate more power, two things are needed: more air and more fuel drawn into the engine’s combustion chamber. It’s worth noting that a specific ratio is required for the engine to operate: 14 parts air to one part fuel.
The air pumped into the combustion chamber is ordinary air at atmospheric pressure. Compression occurs later with the piston’s work, which rises to compress the air-fuel mixture, thus creating a “vacuum.”
The supercharger/turbocharger increases air intake simply by compressing the air to a pressure higher than atmospheric pressure before pumping it into the combustion chamber. With more air intake, more fuel can be pumped into the combustion chamber for the engine to burn and create more energy.
As mentioned above, an important reminder: since adding forced induction puts more strain on your engine and transmission, you might need to make additional modifications to handle such extra stress, like a stronger clutch or cooling system. This varies by each vehicle model, so you should consult a professional on what needs to be done.
Supercharger

Forced induction systems compress the air flowing into your engine. By “forcing” more air, the engine can burn more fuel to produce more power. Later, you’ll encounter a few more aftermarket parts that also increase engine power through the same general mechanism.
A supercharger can add on average 46 to 50% more horsepower and 31% more torque, the rotational or twisting power of a car (as opposed to linear power like a push or pull).
When trying to increase horsepower, remember that this measure is mathematically related to torque. Torque is a crucial measure of an engine’s power, as it represents the load an engine can handle to generate a certain amount of power to turn the engine on its axis. Horsepower equals torque multiplied by RPM (revolutions per minute), divided by a constant. Since there’s usually a limit to how fast you can spin an engine, higher torque allows for greater power at lower RPMs.
Compared to their cousin the turbocharger below, superchargers are easier to install and give you a more instant surge when you press the accelerator. This is because they receive power from a belt connected directly to the engine at the intake. So, when the engine turns, a supercharger immediately gets to work.
This belt-drive function makes them more effective on six-cylinder engines, as opposed to four-cylinder engines. They also don’t require an intercooler as an essential complementary modification, so you’re less likely to encounter overheating or failure issues.
Turbocharger
A turbocharger “recycles” energy from the exhaust flow to power itself, so compared to superchargers, they are extremely efficient. However, due to the nature of this mechanism, there will be a delay or “turbo lag” before you can notice a power increase. This lag during boost buildup doesn’t mean instant response like with a supercharger.
With a turbocharger, you’re typically looking at a 25% horsepower increase, although the peak power might be higher than a supercharger’s in some cases.
Nitrous
Essentially a portable supercharger/turbocharger, this upgrade is another favorite from Fast-and-Furious. It’s also expensive, but many find it more advantageous than a supercharger/turbocharger due to its portability. This might be the most appealing, even decisive, feature since you can carry the kit from one car to another without losing your significant investment.
Being another mod that deals with the air your engine “breathes,” Nitrous is like a can of “air generator.” It essentially creates more air for combustion in the engine, thus generating more power from those combustions.
Note that this engine enhancement is illegal in many countries and states, so check your local regulations carefully before making an investment, and a quite significant one at that. A Nitrous kit can cost you between $900 and over $3,000. On the positive side, however, they can be used as a support for a turbocharger or supercharger to reduce turbo lag and increase final power.
Performance Chips/Aftermarket Software
For almost all factory-turbo cars, a performance chip or tuner is by far the best value for money when it comes to getting more power and efficiency from your vehicle. Pair one of these performance chips with other modifications from this list, and your beastly machine will be spitting fire in no time.
In addition to power, these tuners can also improve throttle response, fuel economy, towing power, gear ratio, air intake index, and much more. Some chips are designed primarily to unlock the engine’s hidden power, which would require more fuel, while others are designed to increase your vehicle’s fuel consumption by optimizing other parameters.
One of the purposes of factory-installed chips, or the Engine Control Unit (ECU), is to ensure everything operates within specifications to comply with emissions regulations. From the factory, the ECU is often tuned conservatively to allow for the use of lower-quality fuels and minimize stress on the engine’s internal components. You can alter these specifications with the aim of optimizing power by installing a performance chip.
A performance chip is aftermarket software, also called a “flash,” and installing a performance chip is also referred to as “flashing your car’s computer.” It’s designed to take full advantage of your engine by adjusting ignition timing to smooth out the power delivery, which would often require premium gasoline to do the job.
Furthermore, they also allow you to easily modify the fuel/air ratio and turbo boost, resulting in an instant power increase without you having to get under the hood and get your hands dirty. Just connect the chip to the OBD-II port to access the information.
These small kits allow for more power, torque, and even better gasoline consumption. Depending on the engine, you can see quite significant power gains. This is a modification often done in conjunction with a turbocharger or supercharger, as the aftermarket software also allows the turbocharger to produce more boost pressure, equating to more engine power.
An important reminder is that if you choose to install a performance chip, make sure to buy it from a reputable tuner, as engines are very sensitive to changes. Also note that software upgrades are often available in stages, where at each stage, you’ll need to select the upgrades that best match your engine’s current setup.
How to Increase Horsepower: Air-Related Methods
You might have noticed a recurring theme by this point: an effective way to increase horsepower has a lot to do with air, and more specifically, as you’ll see later, with both the air your engine “inhales” and the air it “exhales” as exhaust.
Essentially, your car’s engine is a big air pump with a series of deliberate combustions that push as much air in and out as possible to achieve optimal power. Ultimately, the faster, more efficiently, and cleaner your car can inhale and exhale, the more potential you have for power gain.
In other words, if you want to increase horsepower, you’ll essentially need to find different ways to supply air in a larger volume through your engine, and cleaner air at that, while helping your engine exhale more easily. More air means the engine will burn more fuel, and burning more air-fuel mixture means more power generated from the combustions.
The engine enhancement mods below will deal with air intake and exhaust to achieve this general goal.
Velocity Stack
The name intake trumpets comes from the shape of these devices. Photo Credit: Camaro6.
A velocity stack, also called an intake trumpet, is a trumpet-shaped aftermarket part installed on the air inlet of an engine’s intake system, carburetor, or fuel injector to improve airflow.
Velocity stacks improve airflow into the engine’s combustion chamber in three ways.
First, the trumpet shape smoothens the airflow into the intake, allowing the maximum possible amount of air to flow through the given volume of the intake. Second, they smooth the airflow rushing into your intake, and smoother airflow means more air is flowing at any given time. Finally, these small devices purify the air and prevent carburetors without a plenum from vomiting fuel and catching fire.
Although this upgrade is simple and affordable, a properly tuned intake velocity stack would only add about 3% horsepower gain on average as a standalone installation, so it’s usually done with other engine enhancements.
Why are these intake trumpets also installed on the carburetor or fuel injector? Quick recap. A carburetor used to be the most common and basic way for older car engines to get fuel, before the era of fuel injectors or fuel pumps. It mixes air and fuel before being drawn into your engine.
High-Performance Air Filter and Intake
Another quick, cheap, and easy way to give your engine a few extra horses, also used as a support mod, is to replace your air filter with a high-performance filter. It allows your engine to breathe cleaner air, smoothens airflow, and thus generates a small amount of extra power.
Keep in mind that you need to check your state’s regulations, as not all performance air filters are legal in all countries and states.
High-Performance Cold Air Intake
As mentioned above, the colder the air, the denser it is, meaning there’s more air in a given volume. For the same reason, you’ll notice that a balloon might seem to deflate when you take it outside in cold weather, or your car’s tires seem to lose air in winter (the opposite is true, which is why it’s recommended not to overinflate tires in hot weather, as they could burst due to hot, less dense air).
In other words, if you somehow manage to make the air entering your car’s engine denser, there will be more air molecules present to mix with fuel to be ignited for power production.
That’s exactly what a high-performance cold air intake does. Cold air intakes draw colder air into the engine from outside the vehicle. High-performance cold air intakes feature special filters that reduce resistance and unwanted turbulence that would otherwise prevent a steady airflow to the engine. In addition to smoothing airflow, these filters also increase the surface area through which air is drawn into the engine, sometimes up to three times larger than your standard factory air intakes.
Intercooler Kit
As above, an intercooler kit is often installed to complement a turbocharger. Similar to a high-performance cold air intake, installing an intercooler kit will also allow your engine to breathe more air. It does this with the same mechanism: cooling the air supplied to the engine to condense it.
An intercooler, or “charge air cooler,” is an air-to-air or air-to-liquid heat exchange device used on turbocharged and supercharged internal combustion engines to improve their volumetric efficiency by increasing the charge air density through isochoric cooling.
Simply put, a heat exchanger is a device designed to efficiently transfer or “exchange” heat from one matter to another. When a fluid is used to transfer heat, the fluid can be a liquid, such as water or oil, or moving air.
Basically, an intercooler uses air from the atmosphere, circulating it over and around a large number of finned tubes to remove heat from the intake air charge, meaning it reduces the temperature of the air that has been pressurized by the supercharger/turbocharger passing through the intake tubes.

Why is my windshield washer fluid not coming out?
You turn on your wipers during a sudden downpour only to find that the blades are spreading dirt and grime across your field of vision. No matter how many times you press the washer button, no fluid comes out!
Before sticking your head out the window to see the road, keep reading to discover the most common reasons why your washer fluid isn’t flowing and how to fix it so you don’t find yourself in the same situation next time.
We’ll also tell you the one reason why professional help might be needed.
Reasons Why Your Washer Fluid Isn’t Spraying
There are a number of potential reasons why your vehicle’s windshield washer system isn’t working as expected, some of which are slightly more difficult to identify than others. The first step in troubleshooting is learning to identify the potential causes of washer failure.
Here are the most common reasons why your vehicle’s washer fluid isn’t spraying.
#1 – Clogged Washer Nozzles
If your washer fluid nozzles are clogged, any washer fluid pumped through the system itself will not be able to be dispersed onto the windshield. This can occur in a single nozzle or in both simultaneously.
#2 – Pinched Washer Fluid Hose
Any pinch point in a vehicle’s washer fluid hoses can cause a restriction, thereby preventing washer fluid from being sprayed as it otherwise would. Problems of this type are especially common in any situation where a vehicle’s wiper arms have recently been lifted or handled.
#3 – Faulty Washer Fluid Pump
Like any electric motor or pump, a vehicle’s washer fluid pump is prone to failure due to normal wear and tear, with age. This pump can become noticeably weak or stop working altogether, without any warning.
Fortunately, the replacement costs associated with washer fluid pumps tend to be quite reasonable.
#4 – Cracked Washer Fluid Reservoir
Most washer fluid reservoirs are made of plastic, making them prone to cracking and/or chipping. The most common scenario is using the wrong washer fluid during the winter months, thereby allowing the fluid to freeze.
Likewise, impacts from road debris and even some fender benders can cause similar damage.
How to Fix
The following steps can be used to help you diagnose and repair failures related to the washer fluid system.
Step 1 – Inspect All System Components
Begin the diagnostic process by checking for any signs of damage or other irregularities related to the washer fluid system components.
Replace any visibly damaged components and correct any pinch points or restrictions found in the routing of the system’s washer fluid hoses. Additionally, ensure the washer fluid reservoir is filled with the appropriate fluid.
Step 2 – Check for Fluid at the Nozzle Inlet
Next, remove the supply tube from each washer nozzle and check for the presence of fluid when activating the washer fluid pump.
If fluid is present, the vehicle’s washer fluid nozzles are clogged and will require cleaning.
Step 3 – Clean the Nozzles (If Necessary)
If the previous step determines that one or both nozzles are clogged, use one (or a combination) of the methods below to clear things up.
Use a thin wire, a pin, a small sewing needle, a paperclip, or a nozzle cleaning tool to gently probe inside the nozzle holes and loosen any buildup. Be careful not to damage the nozzles.
Alternatively, a thin strand of weed trimmer line can be used. The soft plastic is flexible enough to slip inside without scratching.
Blow out the nozzles using a can of compressed air designed for cleaning electronics. Disconnect the washer fluid hoses and spray it into the nozzle openings to remove any obstruction. Do not spray from the side that connects to the hose, as debris could simply become more stuck.
Flush the system with hot water. Mix equal parts hot water and white vinegar and pour it into the washer fluid reservoir. Operate the washers with the hood open and see if the solution flows freely.
Completely remove the nozzles and soak them in white vinegar or descaling agent to dissolve hardened deposits before reinstalling them.
Replace the nozzles if cleaning methods don’t work. Over time, nozzles wear out or become permanently clogged. New ones can restore full spray power.
Step 4 – Inspect for Leaks
If the above actions yielded no washer fluid, check all washer fluid hoses for signs of leakage when activating the vehicle’s washer fluid pump. Repair any obvious leaks.
Step 5 – Confirm Pump Operation
You must now verify that the washer fluid pump of the vehicle in question is operating as specified.
Remove the washer fluid hose from the pump at the reservoir and carefully inspect the pump itself, while having an assistant operate the vehicle’s multi-function switch. If no fluid is dispersed, further diagnosis will be necessary.
Step 6 – Check Pump Power/Ground
If no fluid was dispersed at the vehicle’s washer fluid pump, it will be necessary to check for the presence of positive 12-volt power and system ground at the pump in question, when the multi-function switch is actuated.
If power and ground are present, but no pump function is observed, the washer fluid pump in question must be replaced. If one or both electrical inputs are absent, further troubleshooting of the vehicle’s control circuit will be necessary, using a model-specific wiring diagram.
When to Get Professional Help
Although most washer systems are rather basic in nature, you must possess a basic understanding of automotive electrical theory to facilitate effective troubleshooting. Furthermore, it is helpful to have at least a handful of basic electrical troubleshooting tools (test light, multimeter, etc.) at your disposal.
If you do not feel comfortable in your understanding of basic automotive electrical troubleshooting or do not possess a general assortment of electrical test devices, seeking the help of a professional is likely the best course of action.
There is no shame in this. In fact, knowing when to consult a professional can very likely save you money and prevent significant frustration in the long run.
One of the most significant components, in terms of expense, that is often mistakenly replaced when attempting to diagnose and repair a washer fluid-related issue is the washer fluid pump itself. This component can easily cost between $25 and $50, not accounting for the time spent during replacement.
For this reason, consulting a professional can prove to be money well spent, when considering the overall cost of a potential misdiagnosis.
How a Washer System Works
A vehicle’s washer system is rather basic in its concept, but complex for anyone unfamiliar with navigating basic 12-volt automotive electrical systems. Therefore, it is imperative to understand the washer system as a whole to conduct thorough diagnostics whenever an issue arises.
Most modern vehicles rely on signals provided by their dash-mounted multi-function switch to facilitate washer operation. Once the designated switch is triggered (usually by pushing or pulling a steering column stalk), power is sent to the washer fluid pump itself, often via a specific relay.
This pump is mounted in the washer fluid reservoir, allowing it to dispense washer fluid via a connected hose whenever it is powered.
The washer fluid is pushed through this corresponding tube under pressure, eventually flowing to each respective washer fluid nozzle. The fluid is sprayed onto the vehicle’s windshield in a targeted manner as it exits through a point of restriction or choke inside each nozzle.
Meanwhile, the same multi-function switch input that triggered the washer fluid pump itself also activated the wipers, thereby wiping a vehicle’s windshield.
Preventative Maintenance and Tips
Here are some tips to help you maintain the optimal operation of your vehicle’s washer fluid system.
Test Periodically – It’s important to test your washers/wipers at least once a week. This helps keep all hoses and nozzles free from restriction.
Use the Correct Washer Fluid – Always check that the formula of the washer fluid you are using is suitable for the seasonal conditions. Some summer-formula washer fluids are not suitable for use in sub-zero temperatures.
Avoid Contamination – When treating your vehicle’s windshield with a weatherproofing product (such as Rain-X) or other protective chemicals, avoid contaminating either of the washer nozzles. Lift both wiper arms when applying such a treatment to avoid this contamination.
FAQ
Can I Add Washer Fluid While the Car is Running?
There is no harm in adding washer fluid to your vehicle’s washer fluid reservoir while the engine is running. This particular system is not pressurized.
Therefore, no risk is posed to your vehicle’s washer fluid system, or to your personal safety, by adding washer fluid on the go.
To add washer fluid to your vehicle’s reservoir, simply lift the corresponding washer fluid reservoir cap and begin filling the reservoir with system-specific washer fluid (a funnel is helpful). Most washer fluid reservoirs are at least moderately translucent, making it relatively easy to determine when the tank itself is full.
Why Does Washer Fluid Not Come Out After a Windshield Replacement?
A pinched washer fluid hose is the most common reason why washer fluid doesn’t spray after windshield replacement.
These hoses easily get pinched when a vehicle’s wiper cowl is reinstalled, thereby causing a blockage inside that hose. This can occur on one or both windshield sprayers, depending on the situation.
How Does a Washer Nozzle Get Clogged?
Washer nozzles can become clogged in several different ways, the most common being related to the accumulation of dirt and debris.
Airborne dust and dirt particles naturally cling to wet surfaces, such as the discharge ends of a vehicle’s washer nozzles. As it dries, this material creates blockages that restrict the flow of washer fluid.
At times, a vehicle’s washer fluid nozzles become clogged with varnish, wax, or other semi-liquid cleaning agents. This is especially true if an overspray has landed on the washer nozzle in question and been left to dry.
