hi, yeasterday when i slowed down for a crossing my 96 t5 started to rev by itself, then when i switched it off and started it again it revved right up to 4,000 so i switched it off again then it refused to start. I unplugged the tps and plugged back in and it started. so i cleaned the throttle body and the tps and it seemed ok till now it just seems to rev up a little inbetween gear changes, still refuses to start unless you leave it ten mins. The temp gauge moves on ignition to the low mark but does not raise even though the pipes are hot and the boost is working as it should.
once i got it running just now it started revving its mind off i unplugged the idle standalization valve and the revs went back to normal.
has anyone had this before, its dangerous to drive if the revs fly up because they dont go down.
please help
thank you in advance
