12. Clean the gasket surface on the intake manifold and the throttle body assembly.

1. Install the accelerator control bracket to the throttle body.

Tighten
Tighten the accelerator control bracket to 3 N·m (27 lb. in.).

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.




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

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

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.




5. Install the throttle body support bracket.

Tighten
Tighten the throttle body support bracket to 11 N·m (8 lb ft).

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.

6. Install the vacuum lines to throttle body as noted on removal.



7. Install the accelerator control (3) and cruise control cables (1) to accelerator cable bracket at throttle body.



8. Install the accelerator control and cruise control cables to the throttle body lever and accelerator control bracket.

Important: Check for complete throttle opening and closing positions by operating the accelerator pedal. Also check for poor carpet fit under the accelerator pedal.

The throttle should operate freely without binding between full closed and wide open throttle. Refer to Accelerator Controls for additional information on accelerator controls.
9. Install the electrical harness retainer clip and harness to the accelerator control cable bracket.



10. Install the IAC valve (1), TP sensor (3), and MAF sensor (1), electrical connectors.



11. Install the air intake tube (1).



12. Install the fuel injector sight shield.
13. Refill the radiator to replace the lost coolant.
