    You may have a Check Engine light on, the engine would rough (similar to pulling off a plug wire) one cylinder would not contribute power to the engine. It may cause black smoke out the exhaust if it is leaking or contribute to high CO or HC emissions from the exhaust tail pipe.
    Just thought using a mechanic's stethoscope (or use a long screw driver placing the handle end up to your ear place the metal tip end of the screwdriver against the body of the fuel injector), get a friend to crank over the engine while you "listen" to the fuel injector listen to each injector at the same point of the injector body. You should hear "click, click, click" as the injector is electrically opened and closed by the computer.They should all sound the same!
