Replacing a fuel injector is not a cheap or easy task, and it's recommended that you hire a professional to do the job. However, before you replace your fuel injector, it's worth checking whether it's simply clogged, as cleaning it might solve the problem. If your vehicle is not getting enough fuel or the supply is uneven, the RPM while idling may drop below the optimal level, resulting in a rough or violent idle. If the RPM falls too low, your car may stall. One of the most common signs of a problem with your fuel injector is the check engine light flashing or blinking, or your engine misfiring.
