What are the Signs of Bad Fuel Injectors?

If your car begins to have starting issues when you turn the key in the ignition, you could be facing a fuel injector problem. Old fuel and gas residue often get caught inside the fuel injector and can result in your ignition not wanting to turn on at startup. With that being said, there are a few simple basics you should know about fuel injectors and how they work.

There are a few basics you should know about fuel injectors and how they work. The fuel injector receives the gas through the fuel pump, which feeds it through. From there, the fuel injector "injects" it into the intake manifold with the utmost precision. After that, both oxygen and fuel mix within that manifold before undergoing the final process of compression within the combustion chamber, which is where it officially powers your engine right at ignition.

Driving problems will sometimes have their roots in dirty or clogged fuel injectors. Since the fuel injector is primarily responsible for the even flow of your gas usage, this may restrict it to the point where driving becomes a task that's nearly impossible due to poor oil flow.

You should keep vigil for the following signs: poor gas mileage, bad or rough idling, and an engine that misfires, the latter of which can result in a "stuttering" reaction where an imbalance occurs between the oxygen that enters the engine and the fuel that your engine relies on.

Idling relies on RPMs, or revolutions per minute, which means that when you experience rough idling, these RPMs may fluctuate even when your car is still. There may even be a sensation of stalling that is reminiscent of a gas shortage, which is a sign that the fuel injector is severely clogged and in need of cleaning.

Low gas mileage is another potential red flag that something needs to be addressed with your car's fuel injector. This could be due to the simple fact that the gas isn't being properly maintained or evenly distributed. When the engine simply won't start, this means that there is no gas being distributed to the right cylinders for use at start up.
