This can often indicate the introduction of excess air into the engine through a crack in the bellows at the turn to the idle air control motor, it is a typical failure. If so, replace the bellows and clear the fault. The part is available online at Realoem.com #13-54-1-437-191 and cost $12.16 plus whatever shipping charges.
