i took out my spark plugs for a compression test (190-190-190-185) and the cone tips have a black at the tip, and the lower body is white. is that too lean? my 02 readings are .97 so that's rich, i was running rich for a long time 1.02. i am on stock injectors btw.

what kind of plugs are you running, at what psi?

its the stock bosch plugs at 5 psi. i'm a little broke right now but my next mod is going to be colder plugs gapped at .35.

my concern is that the white stuff indicate lean conditions.
