yer man get ur AFM cleaned if that doesnt work ur AFM's buggered need a new one or aftermarket same thing happened to me.

And u might want to get a power run to check ur AFRS (AIR FLOW RATIOS) just to make sure everything is up to scatch

dude its either vaccum leaks... ( check on the back of the inlet plenum if that small black hose is fitted nicely and follow it around just to make sure ( i had the same problem) ended up being my custom plenum i had made was warpin under boost and was gettin vac leaks... or its your idle solinoid.. the little gold piece at the back of the plenum also... u may have to replace it... it basically tells the engine when it is cold that it has to idle harder and allow for coldness and say if the a/c is goin and things like that... but when the car is warm its all sweet..very annoying.... but if u say its idleing at 2000rpm.. then it will be a vac leak...almost positive.

hope this helps
