I just cleaned the ISV (idle stabalization valve) on my 964, which looks similar to the Idle control valve on the 911. I just removed the 2 hoses, loosened the hold-down clamps and popped off the electrical connector.
Once removed, I sprayed a healthy amount of carb cleaner inside to loosen all of the gunk, then put 12V power to the connectors to stroke it a few times. You will see the internals shift from ~15% open to 100%, and hear it clicking - this will indicate that it's working (don't try prying the door up as you could scratch the surface and have it jam on you).
Hope this helps!
