Guest Redneck2008 Posted March 27, 2012 Share Posted March 27, 2012 Hi Guys New on here, I've owned my late 1990 MK4 blue & silver anniversary XR3i since 04, she stands end of October to start on May each year, however last year she developed what appears to be a miss fire, I've checked & cleaned the crank sensor but to no avail, she drives excellent but only smooth the faster she goes, bottom end she hick-ups quite badly. Thanks for looking Quote Link to comment Share on other sites More sharing options...

Guest Lee81 Posted March 28, 2012 Share Posted March 28, 2012 Assume its EFi so wont have dizzy cap etc. most likly cause is coil pack. though from your discription sounds more like a fueling problem Quote Link to comment Share on other sites More sharing options...
Guest mass1v Posted March 28, 2012 Share Posted March 28, 2012 I have the same problem with my efi. I have changed most parts other than injectors will be looking into replacing them or getting them cleaned soon . It runs fine when idling but seems to mis / judder when at a constant speed . :/ Quote Link to comment Share on other sites More sharing options...
