  Q: How to clean the throttle body safely and effectively on Buick Rendezvous?

  A:

  Begin the throttle body cleaning work by turning off ignition to avoid throttle blade movement during cleaning that could result in personal injury. The throttle body bore should not receive any tools to prevent harming the throttle valve plate or exposing components to Methyl Ethyl Ketone (MEK)-based solvents. Start by taking out the air cleaner outlet duct before examining the throttle body bore and throttle valve plate for deposits with full throttle valve opening visibility. Cautions against opening the throttle blade using the ON position key because this action might cause a diagnostic trouble code (DTC) to appear. Wipe down the throttle body bore and throttle valve plate with an unsoiled shop towel through GM Top Engine Cleaner (P/N 1052626 or Canadian P/N 993026) or AC-Delco Carburetor Tune-up Conditioner (P/N X66-P) or equivalent cleaning solution. Install back the air cleaner outlet duct as the final stage of repair.

Next, unbolt the nuts and bolts fastening the Throttle Body to the Intake Manifold and retieve the Throttle Body assembly. Clean the surface of the Intake Manifold gasket and the Throttle Body assembly but do not use a solvent as this might damage your parts. If it is needed, install a new gasket and then put the Throttle Body assembly. Fasten it up using the retaining nuts and bolts and tighten them as to 28 n.m (21 lb. Ft). Mount the throttle-body back onto its socket, reconnect the Throttle Body coolant bypass hoses, heater pipe nut, iac valve electrical connector, tp sensor electrical connector courage. To organize everything, it is necessary to reinstall accelerator control cable bracket, air intake collection tube, and tighten clamps. Finally, reconnect the iat sensor electric connection and the breather tube filling the coolant and check for accurate throttle full closed to wide open throttle (WOT) by checking the throttle status while pressing the accelerator pedal with no occurrence of sticking between a full closed throttle and wide throttle.
