AIS2 - Verify Throttle Plate Screw Setting

^ Key off.

^ Cables removed from throttle body linkage per AIS1.

^ Remove the clean air tube from the throttle body and verify that there is no foreign material or debris preventing the throttle plate from rotating to the fully closed position.

^ Verify that the throttle plate stop screw is in contact with the throttle linkage lever arm when the throttle is in the closed plate (idle) position.

^ Does the throttle plate stop screw contact lever arm?

YES -- Go to AIS4. AIS4 - Check For Throttle Body Sticking, Binding, Grabbing

NO -- Do the following adjustment if the throttle plate stop screw does not contact the throttle lever arm:

1. Place a 0.002 inch feeler gauge between the throttle plate stop screw and lever arm. Adjust throttle plate stop screw until it just contacts the feeler gauge.

2. Remove feeler gauge and turn the screw clockwise a half turn.

3. Go to AIS3. AIS3 - Verify TP Sensor In Range
