Guest paulige Posted February 17, 2013 Share Posted February 17, 2013 Hi everyone, i have just become a proud owner of my escort cabrio..1600cc. Its a R reg but its not running well. Its running high and low revs when its warm and smells like its running very rich when warm too. Im just hoping its not a serious problem. Can enyone advise me on what the reason could be for this please? Thanks. Quote Link to comment Share on other sites More sharing options...
Admin Paul Posted February 18, 2013 Admin Share Posted February 18, 2013 ICV - Idle control valve ? Quote Link to comment Share on other sites More sharing options...
gingergman Posted February 18, 2013 Share Posted February 18, 2013 That's what id also suggest, seems to be a common problem with the zetec engine Quote Link to comment Share on other sites More sharing options...
Guest Lee81 Posted February 18, 2013 Share Posted February 18, 2013 You definately have a idle control valve problem as mentioned but you may also have a a inlet manifold/MAF sensor problem. Fix the idle control valve by taking it off and cleaning with wkd 40. If you still have the problem get a new valve. Once thats sorted see how the car behaves. Diagnotics will pinpoint the other issues with sensor failure. These are common too and most cars I see have both problems. Quote Link to comment Share on other sites More sharing options...
