Re: AU stalling when starting cold
Check the throttle butterfly,, they get wet carbon build up there... there will be no air getting past, this is with butterfly shut. Factory clean, there will allways be air getting through there. But now carbon blocking, hence low ,. too low Idle when cold, can't handle the xtra fuel at cold starts. Just remove pipe off so you can clean with wet rag soaked in petrol, give a good clean,, you'll see the shit trapped in there and clean the edging of butterfly too. This is a comon fault I've found on the cars I work on for a living.
