Ive got a 1997 x20xev estate. Has been running fine until now. When engine cold it will only fire up with som throttle. And when it does fire it dies again without throttle. After revving engine a little bit it idles rough at about 700-800. Once engine been running for a couple of minutes it drives and idles just fine. But no fast idle when cold. Does this sound ICV related or is it something else? Stalling and rough idling is only on cold engine.

Ecu coolant temp sensor or IAT

Thanks for the answer. Was planning to check out the ecu temp sensor, but what i didnt mention in my post was that the battery also has been weak. The car starts but only just. Battery charger hasnt really helped either. So decided to go for a new battery before any more checks. Installed new battery today and car started and ran perfectly. Fast idle at around 1100-1200 then after awhile dropped down to 800-900 rpm. Didnt miss a beat.
Didnt mention the battery issue as i didnt think it was related. But now i start to wonder. Can a worn out battery cause this issue? Would have thought once the engine started the alternator would  pick up the slack from a bad battery. But for now all seems to be well... lets hope it continues this way:)

They can start to get pernickety as the voltage drops...
