High Revs when starting!!!
 
I keep noticing my car occasionally when starting revs at between 1 and 2 for a few minutes before coming down to it appropriate level. Anyone got any ideas why? Whats causing this?

Sticking throttle cable/throttle?

opened the bonnet and checked cable and its not that............ i doesnt always do it but it does bug me if i get in the car and there's a few people round. Sounds like i'm an old dear.

Sticking idle control valve could cause that.

I have the identical problem.

Seems to manifest itself more in warm weather - has been fine over the winter but starting again now. Had by cable changed which didn't help. Maybe need to look at idle control valve next...

I have the same problem, comes now and again - couple of blips on the throttle clears it, don't think it's anything serious...

Had the same problem a while ago, it's not done it since though.

Yeah!! I've noticed it more in the warm weather, didnt really do it in the winter, and remeber it doing it a bit last summer too.

With the warm weather approaching my car has started to do this... It dangerously revved up to 4k at lunch time today!

Does anybody have solution to this problem? As you can see here the problem is a not a new one! Moreover I have already tried replaing the ICV to no avail:

Sounds like some temperature sensor is getting wrong readings, maybe.
