The throttle body is part of the vehicle's air intake system. It regulates
the amount of air supplied to the engine for combustion.
The throttle body is calibrated at the factory. If there are problems with
the adjustment of the throttle adjusting screw or with the action, air tightness,
or operation of the throttle, replace the assembly or refer the repair to a
qualified shop.

- Detach the throttle position sensor connector. Disconnect the metering oil
pump connecting rod from the throttle actuating lever.
- Unfasten the throttle body retaining screws and remove the throttle body
assembly from the dynamic chamber.
