• Q: How to clean the throttle body on 2005 Buick Century?

  A: As the first step in cleaning the Throttle Body you must take off the air cleaner intake duct. Check both the Throttle Body bore and throttle valve plate for deposits while opening the throttle valve to examine all parts fully. Use gm top engine cleaner gm p/n 1052626 (Canadian P/N 993026) or equivalent to wipedown the throttle valve plate and Throttle Body bore with shop towels. Throttle Body assembly cleaning should be done without immersion cleaners or strong solvents because these chemicals damage the tp sensor, iac valve, and sealed throttle shaft bearings while also removing vital grease from non-serviceable throttle shaft bearings. Wire brushes and scrapers must be avoided as they will damage components and operators should abstain from using methyl ethyl ketone cleaners since these chemicals can hurt components yet provide no benefit for this task. To clean an excessively contaminated Throttle Body you should disassemble it while using a parts cleaning brush then avoid totally submerging it into any cleaning solution. Follow cleaning by reinstalling the Throttle Body before you attach it to the air cleaner intake duct.
