03 gt stutters and hesitant
My 03 gt has had an issue with stuttering and hesitation as if it's missing. It gets worse the more it's driven (hardly at all after cold start). Seems to be no vaccuum leaks. Already got new spark plugs, coils, and ran two fuel treatments through. Problem won't go away. No codes whatsoever. Any help is very much appreciated
