Can bad fuel injectors cause a knocking noise in your engine?
Getting a knocking noise from my engine and the diagnostic results from my mechanic is stating bad fuel injectors
causing a misfire in cylinders 4,5,8 is that possible a knocking noise could be caused by that
No.... A knock is generally caused by the ignition timing. An injector stuck shut causes a lean misfire which causes the engine to hesitate and loose power but not knock. An injector stuck open causes a rich mixture which will either reduce the chances of a knock or once again cause a misfire. I believe your vehicle is equipped with a knock sensor which is used to prevent knocking or pinging by electronically adjusting the timing. It sounds like the most likely issue is either the knock sensor is faulty or the ignition module inside the distributor is messed up.
