Every plug was in perfect condition for plugs that had been in use for 2 years except this one the number four cylinder. I have NOT dropped in MPG or performance what is wrong with this cylinder, Aall I have got is the P0304 code.

I am at work and I always have problems....work now??? I dont EVER see oil come out the exhaust, and I have not touched my antifreeze for over two years and its perfect, I have never pulled a plug that looks this bad.

I know, and I dont get it, i have only had an issue within the last three weeks and it was just a code, cleared it then two weeks it came back, pulled the plugs put in new wires, amd this was the only bad one, the rest look really good. I just have no symptoms or idea of what this could be![]()
