Get a can of air intake cleaner and a narrow wire brush. Once you get the thing clean, you can check operation by applying suction to the vaccum port. Be sure not to puncture the diaphragm.

Are we talking about IAC or EGR, here?
For the IAC just remove completely and spray it out liberally with intake cleaner.. several times.

I was kinda wondering that too.
Assuming you have engine we're thinking of, this is the IAC:
As stated, take it off (1 electrical plug and 2 different-size bolts), then blast and brush the inner passages until they're clean.
PS: The EGR valve is that round can with the holes on the bottom, hiding on the back side of the manifold. Yours may be reversed, as some models had the intake mounted facing the other way.
IAC. If the coking is heavy, a little brushing helps too.

Will do as you guys say. Thanks again for all tips and help!!!!!!!!!!!!!!!!!!!!1
CJB, Are we talking about the same part here? This idle air control doesn't have a vacum connections on it. It has two cavities on the bottom an a electrical connector. What do you mean check by applying a vacum to test it? thanks!
