Verified

Failed spark plug wires and/or ignition coils can cause intermittent misfires (rough running); the Check Engine Light may also illuminate. Diagnoses of the ignition system will be necessary to determine which components are at fault.

  • Engine light on, no pickup, running very rough. Car was running fine; stopped for a light and then this happened. Glad I made it home!
