  A: Start by disconnecting the cable from the negative terminal of the battery to remove the throttle body. Remove the engine cover and air intake duct. Depending on model year, you will need to disconnect electrical connectors from either TAC or TP sensor and IAC valve. On older models however, you should disconnect accelerator cable as well as cruise control cable from throttle body and take away accelerator cable bracket. However, on newer models, check for damage and if necessary replace them by removing any coolant or vacuum hoses from these bodies; also remove accelerator cable bracket. Move out all bolts/nuts which holds throttle body, throw away old gasket and clean mating surfaces between this one and manifold intake. Use a new gasket for throttle body installation; undo removal procedure in reverse order ensuring that you tighten mounting bolts with specified torque value.
