> no , they dont . so if comp is low and a cyl has a slight missfire at idle and throws a code for it . its not a problem ? i have seen it before and it does cause problems .

my SS with the original motor did that. Idled normal and drove fine but on slight acceleration it would misfire and the SES would blink…then it would go off…

that resulted in 20psi with a tea spoon of oil LOL
