So I pulled out a spark plug to check the gap and I found that one side of the plug was all white and had chunks of stuff on it. This means there there's a lean mixture or too much heat, correct? I know that my motor isn't running hot, so it has to be lean..? All I have is a midpipe, catback, and an fipk2. This wouldnt lean it out too much, would it? My pinging situation has gotten worse too. It'll ping at around 1800 rpm if in a steep gear and some load is put on it. I havn't gotten to change out hte fuel filter yet so I'm hoping that's it. Anything else that it could be?
