Two Black with sut on them, one brown and has lots of buildup and one brown without buildup (I'll have to get new plugs before continuing to test), but the oil in the intake is very scaryMake a new livedata after ECU reset by disconnecing the battery terminal for some time (~30 minutes) to see whether the fuel trims are changed or not. The build up on all plugs should not be the effect of one leaky injector. Anyway, how about you plugs now?
