if you know where your PCV is located, there's a rubber elbo that attaches to the top of the PCV at the back side, driver side of the motor. It may possibly have a worn hole or crack in it allowing an air leak. This will cause the engine to idle high, rough and probably cause the check engine light to illuminate.
