I took out my plugs today to check them out.
My car has felt pretty laggy, and sluggish lately, plus I've been having idle surge, and my A/F meters been showing that my (newly replaced) O2 sensor isn't cycling consistently.
I'm running 15PSI on a 14B and Supra sidemount IC, with piping, ported housing, o2 housing, and mani. Stock exhaust, and stock fuel system. My a/f shows rich at full throttle (second or third rich LED from left)
This is how the plugs looked:

I thought they looked too light, and that black rim below the electrode looks bad? also, its brown on the back of the plug where the white part goes into the metal part that has threads.
Is this bad?
