What should be done to clean the throttle body and throttle plate, and what precautions should be taken regarding mileage on Cadillac STS?

After considerable miles and time, the throttle plate may become dirty behind, with deposits that normally do not pose problems but can interfere with the movement of the throttle valve in excess amounts. This service should not be done in vehicles having mileage below 80 450 km (50,000 mi). Start with removing the engine sight shield and the rear supercharger inlet duct. Use a mirror to inspect the throttle body bore and throttle body plate for deposits, taking sure to open throttle plate for thorough check. Clean the throttle body bore and throttle plate with a shop towel that has been cleaned using GM Top Engine Cleaner (P/N 1052626), AC Delco Carburetor Tune-up Conditioner (P/N X66P), or any other substance of the same kind. Last of all, install the rear supercharger inlet duct and the engine sight shield.
