carbon/oil buildup? or rich?
I went to the track last night, made 12 runs, and on the drive home the car felt funny, slower than normal, and not spooling as fast.
I did a dry compression test today, came out perfect; 180-183. Plugs 1-3 looked perfect, but #4 looks very very dark, like carbon/oil buildup, except the porcelain still looks a toasted marshmallow color, not black. Or is this just rich?
This is an F22 with a t3super60, and the plugs are NGK 7's
