What is the check engine light code? P#### Check for vaccum leaks or manifold cracks. Make sure all fittings are corrosion free and all bolts are secure. Vape in the engine bay a little, see if it sucks fog in somewhere where it shouldn't lol

Re: Idle air control valve
Somethings I suggest checking, if it is P0505 (Idle air control system malfunction)
>IACV or wiring to it
>Gasket leaks at IACV, TB, or intake manifold
>Carbon build up on TB or otherwise sticking TB

Re: Idle air control valve
OK so I have sent about two hours looking over wires and I did not see any thing wrong with any of them from the Engine bay, I made sure there was no carbon build up or sticking tb I just have not looked in to if the gaskets are bad, I will do that this week. Would a bad map sensor cause this issue?

Re: Idle air control valve
I had to replace the intake manifold but that was it. I live in Phoenix,az and right now it is to hot for me to work on it when I can see and I do not have a work light so I would hate to take the intake manifold off to replace the gaskets in this heat.

Re: Idle air control valve
Another method I have found scary useful is vaping into the engine bay and watching the fog move, that'll give away vaccuums as well.

Re: Idle air control valve
Sounds like you have a vacuum leak from replacing the intake manifold.
