yellowish on the spark plugs...anything significant... ?
I swap my plugs after a week of running very rich due to CEL, of course the old plugs were black as well as my exhaust tip...
I swap it out last night, and I just checked mine, it's yellowish color.....
anything I need to know or is it normal ?
