If the engine is not running, but the key is turned to on, should the IAC be making any noise?

The Idle Air Control valve? It makes noise? I didn't think they did, or if they did something would be wrong with it.

Mine is making a sound like morse code. I have never heard it before, but maybe I just didn't notice it.

They often get dirty from the intake. They shouldn't make noise. If it'* clicking that may means it'* jammed and won't go in and out and control the idle like it should.

No noise should be present. Remove and clean...reinstall.

If you need one..holler..there'* like 3 laying around here somewhere.

I pulled the IAC to clean it and it flew apart. The threaded shaft popped out under tension from the spring. Should it come apart like that ?

Nope. It was broke. Most likely the noise you were hearing. The shaft/pintle should never come out.

Make sure you clean out the seat and inwhere the IAC goes before you put the new one in. I use que-tips and carb cleaner until I get virtually not residue on the que-tip.

I pushed the pintle shaft back in and it clicked back in the hole. I reinstalled it until I could get a new one, and there seems to be no problems.

What problems would a bad IAC cause?
