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 injector sight shield. Refer to Fuel Injector Sight Shield Replacement in Engine Mechanical.
2. Drain the radiator coolant. Refer to Cooling System Draining and Filling in Engine Cooling.
3. Disconnect the IAT electrical connector.
4. Remove the air intake tube.



5. Disconnect the IAC valve electrical connector.



6. Disconnect the MAF sensor electrical connector.



7. Disconnect the TP sensor electrical connector.



8. Disconnect the accelerator and cruse controls cables (1) . Refer to Accelerator Control Cable Replacement .



9. Disconnect the electrical harness retainer clip (1) and harness (2) from the accelerator control cable bracket (3) if applicable.



10. Remove the accelerator controls cable bracket. Refer to Accelerator Control Cable Bracket Replacement .



11. Disconnect the vacuum line from the throttle body.



12. Remove the nut (2) from the air injection pipe (1) if applicable if applicable.



13. Remove the exhaust crossover. Refer to Exhaust Crossover Replacement in Engine Mechanical.



14. Remove the throttle body support bracket.



15. Remove the nuts and bolts holding the throttle body to the intake manifold 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.
17. Clean the gasket surface on the intake manifold 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, and new inserts and studs if necessary.
2. Install the throttle body assembly.

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.

3. Reinstall the throttle body 3 retaining nuts and bolts.

Tighten
Tighten the throttle body retaining nuts and bolts to 10 N·m (7 lb ft).




4. Install the throttle body support bracket.



5. Install the exhaust crossover. Refer to Exhaust Crossover Replacement in Engine Mechanical.



6. Install the accelerator controls cable bracket. Refer to Accelerator Control Cable Bracket Replacement .
7. Reinstall the air injection pipe to the throttle body if applicable.

Tighten
Tighten the nut to 10 N·m (7 lb ft).




8. Connect the vacuum line to throttle body.



9. Connect the IAC valve sensor electrical connector.



10. Connect the MAF sensor electrical connector.
11. Connect the IAT electrical connector.



12. Connect the TP sensor electrical connector.
13. Install the air intake tube.
14. Refill the radiator to replace the lost coolant. Refer to Cooling System Draining and Filling in Engine Cooling.



15. Install the injector sight shield. Refer to Fuel Injector Sight Shield Replacement in Engine Mechanical.
