V40 Rough when cold, ok at norm op temp
Hi all.
Desperate for assistance. My 1998 norm asp V40 runs very rough when cold, it has no power until it has run for at least 15 mins and is downright dangerous to drive in that condition. After warm up it runs quite normally thru the whole speed range. It has had multiple visits to workshops, including a Volvo dealer, and has had new plugs, multiple new ignition coils, new HT leads, compression is normal, and displays no fault codes when interogated by an analyzer. Any ideas coz the mechanics don't know.
