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.

Further diagnostic work is needed to determine the cause of the misfire, but the code will isolate the location to specific cylinders.
