Multi engine stalls at idle

I'm having a weird issue with my 2002 Nissan Multi, gasoline engine. The check engine light is on, and the error memory shows a fault related to idle speed. The main problem is that the engine stalls at idle, especially when it's cold. I've checked for vacuum leaks and cleaned the throttle body, but no luck. I suspect it might be a bad idle air control valve. Has anyone else experienced something similar?

Sounds familiar! I had a similar problem with my old 2008 Opel Corsa. The engine would randomly stall at stoplights. Did you check if the intake manifold is heavily contaminated?

Interesting! No, I didn't specifically check for that. Is it a common issue with these engines? And how would I go about checking the intake manifold for contamination?

Well, it was on my Corsa. Turned out the buildup was messing with the airflow and causing the idle issues. I ended up taking it to a workshop, they cleaned it all out and replaced a sensor. Maybe it's worth a look for you too?

Thanks for the tip! I took your advice and checked the intake manifold – it was indeed heavily contaminated. I replaced the idle air control valve and had the intake cleaned at the workshop. Cost me around 425€, but the problem is solved! Really appreciate your help!
