Sorry about that, its an '09 sebring. I changed out the spark plugs and no differance. Plugs were gapped at about .53 which seemed wrong. I gapped at .40, searched online and that is what most had posted. What gap do you think I should go with? I think it probably is the coil that went out. p0304 is cyl 4 misfire. I started the engine and one by one removed the electrical plug from each cyl and noticed one coil had no change in the idle of motor. I switched it with another cyl and then the same coil had the same problem. So I guess it would be that coil. What do you think?
