it is NOT my catalytic convertor, I have removed it and I have excellent exhaust flow, it is running lean, I do not know why, my question is, how can I fix the problem I have of it running lean?
i have no cat, straight 2 1/4" exhaust to a cherry bomb, so there is no restriction. It has a new valve cover gasket and new intake gaskets. Not sure what it could be, EGR valve maybe?
have the same problem?
