my rs idles at 1000rpm when starting then it sits about 900rpm once idle and getting warm then it seem to try and bring the idle down once getting warmer then it will get to below 900rpm and cut out.

also does it when it when putting the clutch in when slowing for traffic just when the car comes to a stop just drops below 900rpm and cuts..

dont know if icv needs cleaning or it idleing to low.
