As you know, a faulty injector is troublesome and can lead to other problems related to the engine and your car’s overall performance.
It is recommended to immediately change your car’s injector if its condition is poor. So, here is some information you need to know to determine if your car has a good or bad injector.
1. Engine misfire or engine hesitation
A faulty car injector will struggle to combat foreign particles that will clog the injector. When the particles have reached a certain amount, the injector cannot fully supply fuel a few times when needed. This will result in lower performance, especially in the engine. The misfire caused by the anomaly is easily felt. This bad sign requires an immediate solution, which is to change or repair the injector because this problem can easily cause the engine to overheat and pre-ignite the fuel mixture.
2. An increase in your car’s fuel consumption
A damaged fuel injector can cause fuel leakage. This is bad because fuel is everything for your car. A faulty car injector will allow fuel to leak through your car’s body or supply excessive fuel when the internal springs are damaged. Gas leaks mean your car will have reduced fuel efficiency, so you have to pay more for gasoline.
3. Poor acceleration (as in, very poor when going from zero to top speed)
A faulty car injector is easily clogged, and a clogged injector will result in irregular fuel supply. This poor flow will cause the car’s engine to fluctuate between low and high RPMs, leading to an unbalanced output rather than a smooth and progressive one.
4. Your car is leaking fuel
Fuel injectors can be damaged from the inside as well as the outside. Internal blockages will damage it from the inside, while external damage can be caused by cracks developed on the outer part of the injector body. This type of damage is quite common, especially on the intake manifold injector. A fuel leak will occur if there is a crack in the injector. Fuel will flow through the body and nozzle, so you can easily see and smell it. Poor engine performance will occur because the fuel is not atomized or sprayed; instead, it will flow as droplets, creating a weak air-fuel mixture.
5. The car is not so “quiet” and “calm” when idling
Of course, a faulty fuel injector will lead to decreased performance while driving. Another thing you need to know if your car has a damaged injector is that it can affect the engine at idle. Abnormal and abrupt fuel supply will cause the engine to idle roughly and unevenly. It is recommended to change the injector because, in the long term, you might face a bigger problem.
As you can see from the issues mentioned above, all can occur if you have a damaged car injector. This will damage your car during your drive and when it is parked. Moreover, your car’s overall performance will be significantly reduced because the fuel supply is abnormal. So, these are 5 symptoms of a faulty injector in your car that you need to know and repair immediately.
