neilw3030 Posted June 21, 2015 Share Posted June 21, 2015 Anybody know how I can avoid the cel light coming on after fitting manifolds and hi flow cats, have fitted lambda spacers which made it better, but still happens periodically with a code indicating lambda so slow to react, I know this is a common problem after fittings cats Quote Link to comment Share on other sites More sharing options...
