REMOVAL & INSTALLATION
See Figures 1 through 7
- Disconnect the negative battery cable.
- Remove the intake duct from the throttle body.
- Disconnect the vacuum hoses and the electrical harness connector(s) from the throttle body.
- Disconnect the accelerator cable and cruise control cable from the throttle cams.
- Label all hoses and disconnect them as necessary.
- Remove the mounting bolts and the throttle chamber from the intake manifold.
- If the throttle position sensor needs to be removed, refer to Driveability & Emissions Controls for the procedure.
- If the throttle position sensor was removed, refer to Driveability & Emissions Controls for the installation procedure.
- Use a new gasket, and mount the throttle body to the manifold. Torque the bolts to 6.5 ft. lbs. (8.8 Nm.) in sequence, and then to 13-16 ft. lbs. (17.7-21.6 Nm.).
- Install and adjust the throttle cable and cruise control cable, if equipped.
Check the throttle for smooth operation and make sure the bypass port is free from obstacles and is clean.
- Connect the electrical connectors and the hoses to the throttle body.
Because of the sensitivity of the air flow meter, there cannot be any air leaks in the fuel system. Even the smallest leak could unbalance the system and affect the performance of the vehicle.
- Connect the air duct to the throttle body.
- Connect the negative battery cable.
- Start the engine, and check for air leaks and proper engine operation.
- Adjust the idle speed as necessary.
During every check, pay attention to hose connections, dipstick and oil filler cap for evidence of air leaks. Should you encounter any, take steps to correct the problem.
