Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery cable to avoid electrical shorts.
  • Allow the engine to cool if it has been running.
2. Clean the Throttle Body
  • Remove the air intake duct from the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle body, focusing on the throttle plate and surrounding areas.
  • Reinstall the air intake duct securely.
3. Inspect and Clean the Idle Air Control Valve (IACV)
  • Locate the IACV, usually mounted on or near the throttle body.
  • Remove the IACV from its housing.
  • Clean the valve with throttle body cleaner and a soft brush.
  • Reinstall the IACV and ensure it is securely fastened.
4. Check for Vacuum Leaks
  • Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
  • Use a smoke machine or spray soapy water around suspected areas while the engine is running to identify leaks.
  • Replace any damaged hoses as necessary.
5. Test and Clean the Mass Air Flow Sensor
  • Disconnect the MAF sensor connector and remove the sensor from its housing.
  • Clean the MAF sensor with MAF cleaner (do not use regular cleaners).
  • Reinstall the MAF sensor and reconnect the electrical connector.
6. Check the Engine Coolant Temperature Sensor
  • Locate the coolant temperature sensor and disconnect the electrical connector.
  • Use a multimeter to test the sensor's resistance according to the specifications in the service manual.
  • Replace the sensor if it is out of specification.
