hopefully you have this problem fixed by now but...chances are the problem was the fast idle valve came loose, theres the plastic "nut" thats threads out over time which causes the fast idle valve to be open all the time...easy fix, doesnt even have to be removed from the intake...just take the two screws off the metal plate on the end to access it, tighten up the plastic nut and put the metal plate back on, youre done.
another thing, which i doubt cause it should be checked often...the coolant is low.
could have blockage in the coolant lines going to/from the fast idle valve and/or iacv
just trying to help, hopefully not repeating someone else here...
