High idel

Asked by Jan 03, 2017 at 03:10 AM about the 2006 Chevrolet Monte Carlo SS

Question type: Maintenance & Repair

Have changed the throttle body and the gas peddle
and still the idel is at about 900 when in park.
Could you tell me what could possibly be wrong?

If the check engine light is on, then have the vehicle scanned for codes, then fix what the code indicates. I suspect a vacuum leak somewhere, a vacuum line or possible intake manifold gasket.
