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 cooling and radiator.
3. Disconnect the air intake tube.



4. Disconnect the IAC valve sensor electrical connector.



5. Disconnect the MAF sensor electrical connector.



6. Disconnect the TP sensor electrical connector.



7. Disconnect the accelerator controls cable. Refer to Accelerator Control Cable Replacement .



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



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



10. Remove the vacuum line from the throttle body.



11. Remove the throttle body support bracket (VIN K only).



12. 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 (VIN K only).



13. Remove the nuts and bolts holding the throttle body to the intake manifold (VIN 1 only).
14. Remove the throttle body assembly.
15. 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. Reinstall the new gasket, and new inserts and studs if necessary (VIN K only).
2. Reinstall 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 retaining nuts and bolts (3).

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




4. Reinstall the new gasket, and new inserts and studs if necessary ( VIN 1 only).
5. Reinstall the throttle body assembly.
6. Reinstall the throttle body retaining nuts and bolts (3).

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




7. Reinstall the accelerator controls cable bracket. Refer to Accelerator Control Cable Bracket Replacement .



8. Connect the accelerator controls cable. Refer to Accelerator Control Cable Replacement .
9. Check for complete throttle opening and closing positions by operating the accelerator pedal. Also check for poor carpet fit under the accelerator pedal.



10. Connect the electrical harness retainer clip (1) and harness (2) to the accelerator control cable bracket (3).



11. Connect the vacuum hose to throttle body.



12. Connect the IAC valve sensor electrical connector.



13. Connect the MAF sensor electrical connector.



14. Reinstall the TP sensor electrical connector.
15. Reinstall the air intake tube.
16. Refill the radiator to replace the lost coolant. Refer to Cooling System Draining and Filling engine cooling.



17. Install the injector sight shield. Refer to Fuel Injector Sight Shield Replacement in engine mechanical.
