How to Properly Clean the Throttle Body on Buick LaCrosse?

Begin Throttle Body service by taking out the air cleaner intake duct. A thorough throttle position check reveals deposits within both the Throttle Body bore and the throttle valve plate when the throttle valve is fully opened. You need to clean the Throttle Body bore and throttle valve plate using a shop towel together with top engine cleaner (GM P/N 1052626) or an equivalent cleaning product. Use a parts cleaning brush for heavy deposits when performing thorough cleaning. Weak solutions and immersion cleaners harm electric components, sensors and seals or o-rings when used with assemblies that contain the throttle position (TP) sensor, idle air control (IAC) valve, or sealed throttle shaft bearings. Non-serviceable throttle shaft bearings can suffer damage through solvent exposure which breaks down their grease protection. Throttle Body components may sustain damage from wire brushes or scrapers while cleaners with methyl ethyl ketone should be avoided because they cause component damage during Throttle Body cleaning. You should replace the air cleaner duct as your final step.
