I have a 99 yukon with a po300 code . new cap, new rotor, new plugs. still miss-fire, when I took the old plugs out i noticed all the plugs on the even side 2-8 were really wet. and the other side was normal. what in the heck does this mean? i can smell the fuel that's not being burned come out the exhaust.
