This is a relatively simple process that generally includes unhooking the old idle air control valve and plugging in the new one. Here are some simple steps to follow:

  • Scan the computer system in the car for codes
  • Check for any vacuum leaks
  • Check electrical connections
  • Remove and replace the idle air control valve if faulty
  • Clean carbon out of intake manifold ports
  • Clear Engine Check light

If you are having trouble with any of this, a certified technician from YourMechanic can come to your location to inspect the vehicle’s idling.
