If the engine runs well otherwise (no misfire, no rough running when you take off from a stop sign, runs better when cold) an idle problem is often caused by the EGR valve. If you have any doubts, run an engine diagnostic test to see what the computer has to say. I recently had this problem and just had it fixed it was my mass air flow sensor so check that, but best to get it tested with diagnostic equipment.
