Revs Stuck at 4000rpm
Noticed a couple of weeks ago that my focus was gently accelerating by itself. Putting the clutch in caused revs to go to 4000rpm for 5 secs then all was OK.
Then after that when first starting off in the morning - (it has only showed this problem when cold) i get to the first junction and when the clutch goes in the revs go straight up to 4000rpm and stay there till i pull off again or get into neutral and bring the clutch up. If i put the clutch in and out the revs go up and down.
Today i felt the car pulling again by itself, put in the clutch, revs straight up to 4000 rpm and they wouldn't settle down so i switched off the ignition. Switched on the ignition again and the revs went straight back up. Turned off/on for a second time and it sorted itself out.
It only does this when cold and the clutch is not slipping and it has only done this when cold.
Any ideas before it goes into ford?
