Best Answer

You need to disconnect the air intake duct, vacume lines, Wire connectors, throttle and Trans down shift, and cruise control linkages. You also need to drain the cooling system down below the level of the T-body. Begin by making sure the engine is cooled down before starting. Assess what is connected to the throttle body and carefully disconnect and remove everything attached to it. The air intake is held together with large hose clamps, and they need to be losened so you can remove the duct. Drain some of the coolant, and remove the coolant pipes from the throttle body. Label and remove the vacume lines, and identify where the wires connect before removing them. After removing all these other things taht are attached to the throttle body, you remove its mounting bolts. The gasket will probably tear, so you need to scrape off the remains be fore you reassemble with a new gasket.
