Disconnect the cable from the negative terminal of the battery. Remove the air intake duct/resonator from the throttle body. Disconnect the electrical connectors from the throttle position sensor and idle air control valve. Label and detach all vacuum hoses from the throttle body. Detach the accelerator cable and, if equipped, the transmission control cable and cruise control cable. On 2006 and later V6 engines, there is one large electrical connector and no accelerator cable. Remove the three mounting bolts and remove the throttle body. Inspect the throttle body O-ring and replace if necessary. Install the throttle body and tighten the bolts to the torque. The remainder of installation is the reverse of removal.

Remove the air inlet tube.

Detach the wire harness connector from the injector by compressing the lock tabs and lifting up.

If the fasteners are properly tightened and a vacuum leak still exists, the carburetor or throttle body must be removed and a new gasket installed.

Remove the throttle body and the pressure regulator mounting screws. Remove the housing, spring, spring seats, diaphragm, and pivot. Clean the housing and reinstall the components, ensuring the diaphragm vent hole aligns with the throttle body and housing vent holes. After replacing the regulator and installing the throttle body, check for leaks and adjust the fuel pressure.
