Notice: Do not use solvent of any type when cleaning the gasket surfaces on the intake manifold and the throttle body assembly, as damage to the gasket surfaces and throttle body assembly may result.

1. Remove the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement .



2. Drain the radiator coolant. Refer to Cooling System Draining and Filling
3. Remove the air cleaner intake duct (3). Refer to Air Cleaner Inlet Duct Replacement .



4. Remove the MAF sensor electrical connector (3) from the MAF sensor (4).
5. Remove the IAT sensor electrical connector (2) from the IAT sensor (1).



6. Remove the IAC valve sensor electrical connector (4) to the IAC valve (1).
7. Remove the TP sensor electrical connector (3) to the TP sensor (2).



8. Remove the accelerator control cable (3) from the throttle body lever (1). Refer to Accelerator Control Cable Bracket Replacement .
9. Remove the cruise control cable from the throttle body lever. Refer to Cruise Control Cable Replacement .



10. Remove the vacuum hose (1) from the fuel pressure regulator (2).



11. Remove the PCV valve hose (1).
12. Remove the the throttle body vacuum port hose (2).



13. Remove the throttle body coolant hoses.
14. Remove the accelerator controls cable bracket. Refer to Accelerator Control Cable Bracket Replacement .
15. Remove the nuts and bolts holding the throttle body to the intake manifold (1) using a wrench on the manifold side of the inserts to prevent the inserts from rotating in the manifold casting.
16. Remove the throttle body assembly (3).
17. 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 the new gasket (2), and new inserts and studs if necessary.
2. Install the throttle body assembly (3).
3. Finger start the top nut.
4. Install the the accelerator controls bracket (4).
5. Finger start the accelerator controls bracket and remaining throttle body retaining nuts and bolts.

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.

Tighten
Tighten the retaining nuts to 12 N·m (106 lb in).

Tighten
Tighten the retaining bolts to 9 N·m (80 lb in).
