Hi, I have had my 1998 escort for 1 week now, and it keeps revving on its own, seems to only happen in first and second gear, and only when i set off from junctions, this can be dangerous as i found out when i got stuck in the middle of a roundabout.
when the revs shoot up to about 5000 revs i turn ignition off but the car still runs screaming its balls off for about 4 seconds, it does start back up straight away though.(in a huge cloud of white smoke trailing behind me)
Today it has started to smoke just behind the turbo with white smoke, not a lot, but enough to get worried.

PLEASE HELP.
