It has always does this and one day when I let it idle for a long time, the engine just died. Has anyone experience this before? I've had similay experiences with my E39 540i V8 with M62 engine It was a combination of: 1. Dirty, clogged ICV (idle control valve). Cleaned with carb cleaner 2. Faulty coil causing misfires. Replaced coil. Whether the above applies to your car is dificult to determine, as you don't mention what ytpe of car or engine you are talking about !!

tonylauno1 7 Report post Posted July 8, 2008 A friend gave me a bottle of Motorup, and now it seems like it only does it after 4-5 mins of idling. I guess when the engine switches from cold to warm, he reckons it might be the variable timing. Anyway, thanks for the offer. Thanks for the offer, I'll wait till it gets worse or at least does it on every cold start then I'll come and see you. Would be easier to diagnose.
