ICV goes to full closed position after turning key to ignition :/
Hey you all
my car has a slightly high (but stable) idle speed, around 1000-1100 RPM. I measured the resistance across the pins and it is within spec. The valve hums when I turn the key to ignition.
But according to the Bentley Manual, if you close the valve manually and then turn the key, the valve should return to half open. In my case, it returns to fully closed...any ideas?
Thank you
