02 sensor CEl
I read on or vfaq about removing the CEL light by installing a spark plug antifouler. The project is pretty straight forward but then again they were doing it on an evo. I know we have 2 oxegen sensors one on the exhaust manifold and one on the exhaust. I know one is there for emmissions and one is to tell the car if its running rich or lean. I'm pretty sure the second one is emissions and that doing the spark plug antifouler on it wouldnt affect performance but I want to be sure. Thanks guys.
