[QUOTE="jarance, post: 179266, member: 21"] First and foremost, your idling speed problem and the gearbox have nothing to do with each other. i.e. the problem is not related. When the gearbox is is in Neutral or park position, do you still have idling speed problem. It YES, then your problem is not due to the gearbox being faulty. If after changing the ICV and you still have the engine dying off, then concentrate on the AFM as advise by some of the forummers. (if your car have AFM). To check the AFM condition, just removed the air filter and peep thru the box to see the vane of the AFM. If you cannot see the vane, switch off the engine. If you cannot see the vane coming back, then your vane is stuck at the open position. Try banging the top of the AFM and see whether the vane come back and close the AFM inlet. I have service my AFM before by cleaning and filling the edge that is touching the body of the AFM body. So far been more than 1 year without problem. [/QUOTE]
