The Fuel Injector is a very crucial part of a car. It takes up fuel from the Fuel Pump and mixes it with an optimum amount of air to ignite your car’s engine. It is the single point of contact between the fuel pump and the engine. Here are five signs that tell you that your fuel injector is failing.
1. If the Engine Misfires
A faulty fuel injector will create an imbalance between the amount of air and fuel in the engine, which may cause engine misfires—an engine misfire results in pats and puffs from the exhaust and inconsistency in acceleration.

2. A sudden drop in Fuel Efficiency
A sudden drop in fuel efficiency is a massive sign of a failing fuel injector. This happens because the fuel injector might pass more than the required fuel to the engine. Rollover your car to your nearest GoMechanic Workshop and get your Fuel Injector checked by experts!

3. Vibrations while Idling
Unusual vibrations at idle RPMs are also a very common sign of a malfunctioning fuel injector. Since there’s no proper regulation of the amount of fuel entering the engine, you might notice higher vibrations while idling.
4. Erratic movement in the RPM Needle
Adding to the point above, erratic movement in the RPM gauge is also a result of a faulty fuel injector. If you notice that your RPM needle is going high up even when you are not accelerating as much, the injector might be broken.
5. Car not starting
Okay, this one is pretty self-explanatory; if there is no fuel entering the engine, of course, it won’t start. To ensure that this is a faulty injector at work, look out for the slight “ZZZZ” sound that comes on when you turn on the ignition. If you do not hear this, then the injector is most definitely broken. Worry not, though; you’ll find the best deals on a new fuel injector HERE!
