Is it throwing any codes? Sounds like a massive vaccuum leak to me. These cars are bad about PCV rubber boots/lines leaking...

The car should die when the IAC is unplugged, as with it closed, there should be no air entering the motor. If it doesn't die, it's either stuck, or there is air getting in somewhere...

I agree could be a very bad vacuum leak. They are notorius for it. On another hand, unless it's a huge vacuum leak it could be a fuel pressure problem.

Throttle plate should have a minimum opening stop to set a curb idle (typically around 500rpm or so) that the IAC then augments to varying degrees depending on temperature.

Dang, you are just correcting me all over the place today!

Every Ford I have ever had has died when unplugging the IAC, or, come very very close to it, and then eventually dying..

 

[fastpakr]

Certainly not my goal. And that's not terribly surprising. At 500rpm, it should be close to dying. It's not nearly as open as an idle adjustment screw would be on a carb where there was no separate idle controller.

 

[BlackBII]

Gotcha.

So, from this point, we can assume that if the IAC is unplugged, and your truck is still idling higher than 500rpm or so, you may have a vaccum leak, or someone has been messing with the curb idle screw.

 

[fastpakr]

Best of luck.

Take Carb cleaner and spray around the intake ports where they bolt to the head. I had one do something similiar and the intake gasket was bad, if you spray carb cleaner on it and it speeds up thats the problem.
