Q: Car misfires

asked by on

My car is misfiring.

Misfires are common and can be caused by things like bad spark plugs, spark plug wires, coils, bad injectors, or low compression. When the ECM detects a misfire, a code is usually set. A qualified mechanic, such as one from YourMechanic, can extract the code and pinpoint which cylinder that is not working. Further diagnostic work is needed to determine the cause of the misfire, but the code will isolate the location to specific cylinders.
