2. Drain the radiator coolant. Refer to Draining and Filling Cooling System in Cooling System.
3. Remove the fuel injector sight shield.




4. Remove the electrical connector (2) from the Intake Air Temperature (IAT) sensor (1).




5. Remove the intake air duct from the throttle body.




6. Remove the electrical connector from the idle air control (IAC) valve.




7. Remove the electrical connector from the Throttle Position (TP) sensor.




8. Remove the electrical connector from the Mass Air Flow (MAF) sensor.




9. Remove the cruise control cable (1) from the accelerator control cable bracket (2).




10. Remove the accelerator control cable (1) accelerator control cable bracket (2).




11. Remove the cruise control cable (2) from the throttle body lever (3).




12. Remove the accelerator control cable (2) from the throttle body lever (3).




13. Remove the electrical harness retainer clip (1) from the accelerator control cable bracket (3), if applicable.




14. Remove the vacuum hoses from the throttle body. Note the location of the hoses.




15. Remove the nut (2) from the air injection pipe (1), if applicable.
16. Remove the exhaust crossover.




17. Remove the 3 nuts and bolts retaining the throttle body to the supercharger.




18. Remove the throttle body assembly.
19. Remove the accelerator controls cable bracket, if replacing the throttle body.

NOTE: 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.

Use care in cleaning the gasket surfaces on the intake manifold and the throttle body assembly, as sharp tools may damage the gasket surfaces.

20. Clean the gasket surface on the supercharger and the throttle body assembly.

INSTALLATION PROCEDURE

NOTE: Refer to Fastener Notice in Service Precautions.




1. Install the accelerator controls bracket to the throttle body, if necessary.

Tighten
Tighten the bolts to 16 N.m (12 lb ft).




2. Install the new gasket, and new inserts and studs if necessary.
3. Install the throttle body assembly.
4. Install the throttle body retaining nuts and bolts.

Tighten
Tighten the nuts and bolts to 10 N.m (89 lb in).

5. Install the exhaust crossover.




6. Install the vacuum hoses to the throttle body.




7. Install the accelerator control cable (1) to the accelerator control cable bracket (2) at the throttle body.




8. Install the cruise control cable (1) to the accelerator control bracket at the throttle body (2).

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




9. Install the accelerator control cable (2) to the throttle body lever (3).




10. Install the cruise control cable (2) to the throttle body lever (3).
11. Check for the correct throttle opening and closing positions by operating the accelerator controls pedal.
12. Check for correct carpet fit under the accelerator controls pedal.




13. Install the electrical harness retainer clip (1) and the harness to the accelerator controls bracket (3), if applicable.




14. Install the electrical connector to the MAF sensor.




15. Install the electrical connector to the TP sensor.




16. Install the electrical connector to the IAC valve.




17. Install the intake air duct.

Tighten
Tighten the clamp to 2 N.m (18 lb in).




18. Install the electrical connector (2) to the IAT sensor (1).




19. Refill the radiator to replace the lost coolant. Refer to Draining and Filling Cooling System in Cooling System.
20. Install the fuel injector sight shield.

Tighten
Tighten the nut to 2 N.m (18 lb in).
