My Cel light comes on randomly with the cylinder 6 misfire code but the vehicle runs and drives fine. Ive replaced the plugs, and cap n rotor before when it did idle rough but now it seems fine.

 

Have you changed out the spark plug wires?

 

going to test the wires today to see if they are going bad.

 

I have always changed the plug wires the same time I change the spark plugs... Now did they truly needed changed??? I just made it a habit and be done with it lol!
