Checking Minimum Idle Airflow

NOTE: After each repair, perform TEST VER-2 .

Turn ignition off. Disconnect PCV valve hose from vacuum nipple. Cap PCV valve nipple. On 3.3L engine, disconnect 3/16" idle purge hose from throttle body. Install Vacuum Fitting (6457) to intake manifold PCV nipple. On 3.5L, disconnect 3/16" idle purge hoses on both throttle bodies. Install Vacuum Fitting (C-6457) to each purge nipple on both throttle bodies. Go to next step.
On all engines, start engine. Allow engine to reach normal operating temperature. Using scan tool, actuate minimum airflow. If vehicle odometer indicates more than 1000 miles, go to step 4). If vehicle odometer indicates less than 1000 miles, go to next step.
On 3.3L, if vehicle odometer indicates less than 1000 miles, and engine speed is not 540-840 RPM, replace throttle body. On 3.5L, if vehicle odometer indicates less than 1000 miles, and engine speed is not 700-1000 RPM, inspect throttle body and check throttle body adjustments. Repair as required. On all engines, if engine speed is 540-840 RPM (3.3L) or 700-1000 RPM (3.5L), minimum airflow is normal. Test is complete.
If vehicle odometer indicates more than 1000 miles in step 2) and engine speed is 600-840 RPM (3.3L) or 750-1100 RPM (3.5L), minimum airflow is normal. Test is complete. If vehicle odometer indicates more than 1000 miles in step 2) and engine speed is not 600-840 RPM (3.3L) or 750-1100 RPM (3.5L), go to next step.
On 3.3L, replace throttle body. On 3.5L, inspect throttle body and check throttle body adjustments. Repair as required.
