Clean the throttle body. Subject: Engine Stalls When Air Conditioning Is Turned On at Idle

Models: 2004-2007 Buick Rainier

2002-2007 Chevrolet Trailblazer and Trailblazer EXT

2002-2007 GMC Envoy, Envoy XL and Envoy XUV

2002-2004 Oldsmobile Bravada

2005-2007 Saab 97x Engine may stall with the air-conditioner on and or while adding additional loads to the engine at idle. An example of an addition load would be turning the steering wheel left or right with the air-conditioning on. This type of stall usually occurs during idle or slow parking lot maneuvers. This concern may not set any diagnostic trouble codes.

Recommendation/Instructions:
Clean the throttle body bore and the throttle valve plate using a clean shop towel with GM top engine cleaner, GM P/N 1052626 (Canadian P/N 993026) or AC-Delco Carburetor Tune-Up Conditioner, P/N X66-P, or an equivalent product.
