My fiesta st 2.0L is over revving, its accelarates itself without touching the pedal. When stopping it revs upto about 3000 revs and only drops when you dip the clutch. We were advised to get a new throttle body but this hasn't made any difference. Can anyone have any ideas?

I would definitely have your Idle Air Control valve checked/replace....I've had them stick at around 3000 rpms, even while driving, and couldn't stop the car without turning off the ignition first....
The Ford Fiesta certainly isn't the most affordable small car, but especially if you consider the Fiesta's stylish appearance and surprisingly stout feature lists, it's one of the better ways to downsize-without feeling like you're moving downscale, that is.----------------------------------------------------------------------------------------- Car Diagnostic Tools
hi chris, this is one of the first fuzzy logic auto boxes to be fitted to a european car,followed by vw(zf make them,as do borg warner)
try this, just to make yourself aware of whats happening,without touching the gas,put the car in drive and let it accelerate itself ,right upto top gear,stop, then using 1/3 pedal,do the same,stop, then floor it,you will feel the differances right away,(the car will try to make you drive more smoothly,saving gas).other than checking fluid level,
every 6k,the only fix,if needed, is a rebuild.
but,if you know why it baulks in 2nd,(big drop in revs,between 1st and 2nd),you will feel better.
this is not in any handbooks.

mmm spay some flammable liquid around the inlet manifold whilst its running see if it revs up ..if it does may be an air leak. note dont spay near air filter..
I have same problem with 2002 laguna. Before warning lights and revving at 2000rpm starts car feels jumpy. Have to stop, take card out of slot and back again to start without fault. Happens a few miles drive later again. Anyone got a solution?
