I know you said it idles when it is warm at 500rpm but do you notice any flutering at all? Anything different? Is it at all slugish?

Its just kind of odd how the IACV works fine once you are warm but during cold start it doesnt seem to work.

Do you notice any wires loose? Did you have any electrical problems before? I would try changing the IACV first then if that doesnt solve the problem we can trouble shoot some more.
