gudgo1 Posted October 13, 2009 Share Posted October 13, 2009 I have got a 03 mondeo 1.8 zetec and when I am on a long journey the engine will miss fire when I slow down. It wil run very smoothly along the motorway but on the normal road after the run it feels like its firing on 3 . So I stop turn the car off and back on and it runs as sweet as a nut then. The engine management light will come on sometimes afterwards but goes away two days later. Quote Link to comment Share on other sites More sharing options...

HT lead faulty, try Halfords =] 4. spark plug faulty, once again Halfords, 5. igniton system, worst case senario take to a garage Quote Link to comment Share on other sites More sharing options...
