It all started after having the engine pressure washed. Already replaced plugs and wires and it help for a day but now its back. Could it be the coil pack? Is there anyway to test it? Thanks, John 1998 ContourLX V6 ATX Cats Gutted+MIL Eliminators Grandma gave me the finger

Put an inductive timing light on each wire when it happens and look for the missing output. "Those who cannot remember the past are condemned to repeat it" -George Santayana
