Well it seems I have another issue that may be related to the throttle body idle symptom. As stated before.......... after cleaninng everything it started and idled perfect. Today I started it and would not idle. This time it idles fine after it warms up. Is there a temperature sensor that envokes a choke or am I on the wrong track?

 

If you had another thread you should add this as a reply so we know where your at. Did you replace the IAC? If not thats your problem.

 

Yes your correct. I should have. Sorry and thanks ................

 

My 2000 Lariat had the same problem. I had the IAC replaced...problem solved. MIne last over 200,000 miles.

 

You were correct. That solved the problem, but what a B___h getting it out and getting the new one in. Had to use a ignition wrench and lay on top of the engine. Thanks guys ..............
