9. Disconnect the fuel pressure regulator vacuum hose (1).



10. Disconnect the PCV valve hose (1).
11. Disconnect the throttle body vacuum port hose (2).



12. Disconnect the throttle body coolant hoses.
13. Remove the accelerator controls cable bracket, leaving the accelerator and cruse cables connected. Refer to Accelerator Control Cable Bracket Replacement .
14. Remove the upper nut holding the throttle body to the intake manifold (1).
15. Remove the throttle body assembly (3).
16. Clean the gasket surface on the intake manifold (1) and the throttle body assembly.

Important: The throttle should operate freely without binding between full closed and wide open throttle.

1. Install a new gasket (2), and new studs if necessary.
2. Install the throttle body assembly (3).
3. Finger start the top nut.
4. Connect the throttle body coolant hoses.
5. Position the accelerator controls bracket (4).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

6. Finger start the accelerator controls bracket retaining nuts and bolt.

Tighten
Tighten the three throttle body retaining nuts to 10 N·m (88 lb in).

Tighten
Tighten the accelerator bracket retaining bolt to 13 N·m (115 lb in).
