could be TPS? even IAC? I think even a buggered EGR could possibly do some funky stuf. But i'd say its definetly a sensor or something if it just started this.
IAC would make sense to me...and its a b#$% to change so that'll be the last thing they try.
Also double check the tube at the rear of your intake mani. from the PCV, sometimes those get worn out and get a hole, that could cause a vac. leak.
