Right now I am fairly certain I don't have any vacuum leaks. It's possible though.

I've got a scan I did earlier saved on my laptop. I'll just grab it in a moment and see if I can get it posted up.

This is too weird, as that's exactly what I'm seeing. I've also noticed it isn't as bad when the engine is cool (which I have a theory about that, too).

You can see my summary right here:

Iron, what should the IAC be showing etc so I can check that stuff out...

Strange.... for all I know we might have pretty much the same problem. Hopefully it won't take long to figure them both out.
