Is there a gasket between the throttle and intake manifold of 2009 Buick Excelle?

Yes The throttle body gasket is located between the intake manifold and the throttle body and mainly plays a sealing role. When cleaning the throttle body, the maintenance personnel will completely remove the throttle body for cleaning, and the sealing gasket can also be removed, so that the gasket will not be damaged when cleaning the carbon deposit. Contact with carburetor cleaner and gasoline should be avoided for these sealing gaskets. The gasket will expand after contacting with the cleaning agent, and the sealing performance may decrease after installation and use, or it may not be installed properly. If the carbon deposit is cleaned without disassembling the throttle body, the carburetor cleaner will not have any influence on the gasket.
