    Q:
    How to remove the Throttle Body on Chevrolet Trailblazer? Posted by Kirk Z.
    A:
    To remove the throttle body on V6 models, start by removing the air intake duct and resonator and disconnecting the electrical connector and the EVAP canister purge line. Then, remove the mounting bolts along with the throttle body. Make sure to remove any old gasket material from the throttle body and intake manifold and install a new gasket.
