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...

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.S50 - '99 Estoril/Estoril-Black

I am going to replace the idle control valve again with a known "good one". This high revving fault is a real pita and needs to be sorted...
This fault also shouldn't be confused with the acceptable "normal" revving on start-up from cold, (we all would expect possibly up to 2k revs)....However, this fault however is something else.
Glad i'm not the only one that has experienced it.
Another point is that after the aforementioned high revving the car runs really well (better than usual). Almost as if a sticky gate / switch has been cleared...Out: 99 S50 Titan Silver V876 KKO
