1990 Chevrolet Lumina Repair Question
Chevrolet Lumina Body Problem
Remove the air cleaner assembly along with the necessary duct work to gain access to the TPS. Unfasten the TPS attaching screws. If the TPS is riveted to the throttle body, it will be necessary to drill out the rivets. Remove the TPS from the throttle body assembly. If equipped, inspect the TPS O-ring and replace if necessary. With the throttle valve closed, install the TPS onto the throttle shaft. Rotate the TPS counterclockwise to align the mounting holes. Install the retaining screws or rivets. Tighten the retaining screws to 18 inch lbs. Install the air cleaner assembly and any other duct work that was removed.
