How to replace the throttle body assembly on 2005 Cadillac STS?

The first step for Throttle Body assembly replacement starts with removing the fuel injector sight shield and air cleaner outlet duct. Begin by disconnecting power from the Throttle Body electrical connection followed by tightening the mounting bolts to remove the Throttle Body system along with its gasket from the water housing. Discard the existing gasket because it is no longer usable. The use of carburetor cleaner is appropriate for removing deposits during setup but users must avoid cleaners which include methyl ethyl ketone because damage to components could occur. Mount the Throttle Body assembly to the water housing using new gasket while tightening mounting bolts to 10 n.m (89 lb in). First reattach the electrical connector to the Throttle Body assembly then install the air cleaner outlet duct before returning the fuel injector sight shield.
