I wonder if anyone can help...
The engine in my E30 316i is cutting out on start up and will only idle after it starts to warm up, with the idle speed increasing slowly to correct level.
I have played with the idle control valve and worked out that it is permanently closed when the ignition is on. I tried running with the valve switch disconnected and the idle speed increased but the low end torque suffered and missfired sometimes.
Does anyone know how this issupposed to work? It used to start fine, idling slightly faster than normal until it warmed up then itwould idle at the correct level.
