my check engine light came on the other day and i was hearing a ticking in my engine. i went and had a test run on my car and said cylinder 4 was misfiring. i did a tune up changing the plugs and wires which had not been done since the car was manufactured and my car has 94,000. the car runs a hell of alot better but the cylinder is still knocking. anyone have any suggestions on what i can to fix it or what it might be?
