Focus RS mk1
Can any of the boffins on here help, i have a missfire but it only happens high up the revs around 5000rpm. It misses the whole car will shake but only for a second or so then it will be ok revving all the way to the limiter.
Its only happened in 1st and 2nd gear :S. When it misses its pretty bad shaking the whole car, so far i have changed plugs, leads, coil pack and 1st oxy sensor in the exaust. im thinking maybe injector/s or TDC sensor?
Im just baffled as to why it only happens high in the revs and for a second or so then its fine.
Any help would be great thanks.
