Check for vacuum leaks, clean out the area around the throttle plate (inside the throttle body) with carb/brake cleaner, flush out AIC with carb cleaner and then a light lubricant (wd40 works). If it still happens, you may need a new aic.
COuld be the AMM, but that's less likely considering the symptoms.
Does the idle start that high right when you start the engine, or does it come on after boost, or what? If it comes out after a boost situation, your BPV could be leaking vacuum.
The only thing is I think these fellas are right about it being the AIC - usually a vacuum leak on these things only raises it to 12-1400 rpm, 2000 seems a little high.
