- Set parking brake and block front wheels. Warm engine in Park or Neutral until cooling fan cycles on and off at least once. Ensure all accessories are off. Remove air cleaner assembly and disconnect PCV hose from PCV valve. Attach 0.185" Fixed Orifice Air Metering Fitting (6714) into disconnected vacuum line in place of PCV valve.
- Disconnect idle purge vacuum hose from front of throttle body next to MAP sensor. Cap throttle body vacuum fitting. Connect DRB to DLC. Start engine and allow to idle for at least one minute. Using DRB, access MINIMUM AIRFLOW. When accessed, DRB will count down to stabilize idle RPM and display minimum airflow idle RPM. See THROTTLE BODY MINIMUM AIRFLOW IDLE SPECIFICATIONS table.
- If throttle body minimum airflow idle speed is not within specification, check for vacuum leaks. If there are no vacuum leaks, replace throttle body.
