16. Remove the throttle body assembly.
17. Remove the accelerator control bracket, if replacing the throttle body.

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.

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

### Installation Procedure

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.

1. Install the accelerator controls bracket.

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

Important: The throttle should operate freely without binding between full closed and wide open throttle. Refer to Accelerator Control Cable Replacement or Accelerator Pedal Replacement .

8. Install the accelerator control cable (2) to the throttle body lever (3).
9. Install the cruise control cable (2) to the throttle body lever (3).
10. Check for complete throttle opening and closing positions by operating the accelerator pedal.
11. Check for poor carpet fit under the accelerator pedal.
12. Install the electrical harness (2) retainer clip (1) and harness to the accelerator control bracket (3).
13. Install the vacuum line to throttle body (1).
14. Install the MAF sensor electrical connector to the MAF sensor.
15. Install the TP sensor electrical connector to the TP sensor.
16. Install the IAC valve electrical connector to the IAC valve.
17. Install the intake air duct (1).

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

18. Connect the IAT sensor electrical connector from the IAT sensor.
19. Install the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement .
20. Refill the radiator to replace the lost coolant. Refer to Cooling System Draining and Filling in Engine Cooling.
