Question about 1999 Dodge Durango
Check to make sure the IAC valve is not stuck in the bore in the throttle body. With the air snorkel removed from the throttle body you should be able to look down at the throttle body. Just to the rear of the throttle plate there will be an opening. Can you see the pintle of the IAC?
Take a small screwdriver and carefully push the pintle the drivers side. then try starting the car. If it starts and idles you need to remove the IAC, clean the air in the throttle body that the IAC uses, and try cleaning the IAC.
If you can see visible wear on the IAC pintle head replace it. The combination of the air passage being carboned up and the worn out pintle head are what cause it to get stuck.
