1. Drain coolant. Refer to Cooling System Draining and Filling in engine cooling.
2. Remove the air intake breather tube.
3. Connect IAT electrical connector.
4. Loosen both clamps on the air intake duct.
5. Remove the air intake duct.



6. Disconnect the IAC valve electrical connector.



7. Disconnect the TP sensor electrical connector.



8. Disconnect the accelerator controls cable. Refer toAccelerator Controls Cable Replacement .



9. Remove the accelerator control cable bracket. Refer toAccelerator Controls Cable Bracket Replacement .



10. Disconnect the throttle body coolant bypass hoses.
11. Disconnect the heater pipe nut at the throttle body.
12. Remove the nuts and bolts holding the throttle body to the intake manifold.
13. Remove the throttle body assembly.

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. Clean the gasket surface on the intake manifold and the throttle body assembly.
2. Reinstall a new gasket, if necessary.
3. 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.

4. Reinstall the throttle body retaining nuts and bolts (3).

Tighten
Tighten the throttle body retaining nuts and bolts to 28 N·m (21 lb ft).

5. Connect the throttle body coolant bypass hoses.
6. Connect the heater pipe nut at the throttle body.



7. Connect the IAC valve electrical connector.



8. Connect the TP sensor electrical connector.



9. Reinstall the accelerator control cable bracket. Refer toAccelerator Controls Cable Bracket Replacement .



10. Connect the accelerator and cruse controls cable. Refer toAccelerator Controls Cable Replacement .



11. Reinstall the air intake duct.
12. Refill the coolant. Refer to Cooling System Draining and Filling in engine cooling.

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

13. Inspect and check for complete throttle opening and closing positions by operating the accelerator pedal. Also check for poor carpet fit under the accelerator pedal.
14. Tighten both clamps on the air intake duct.
15. Reinstall the breather tube.
16. Connect the IAT electrical connector.
