Does anybody know how to test the Idle Air Control Valve attached to the throttle body? I'm beginning to suspect my no start condition is more related to this than vacuum leaks; while looking around I noticed coolant leaking out near the IAC. This would be a huge help, if it really did **** the bed than that may be why my car wont start. To further enforce my new theory, when I unplugged the IAC valve and tried to start the car, I got the same result as when it was plugged in. As always, any suggestions are welcome I am no expert!
