IACV Problems

I was wanting to know what the RPMs for cold start up is and what controls it. If the IACV controls it, does it also control the idle with it using the idle up valve?

Thing is the car doesnt have a good idle after warmed up. It idles at 1200 then at around 200 through 500. Sometimes it will die at a stop or pulling out. If i unplug the IACV during cold start up it idles down to about the culprit idle as above. Is this a electrical problem or a IACV problem? If it needs cleaning like i have read about then why does it idle at 1200 during cold startup? Thanks.
