Solution

1. Preparation

Gather tools and parts necessary for the repair.
Disconnect the vehicle's battery to prevent electrical shock and accidental acceleration.

2. Inspect and Clean Throttle Body

Remove the Throttle Body:
- Disconnect the air intake duct from the throttle body using a socket set.
- Unplug the electrical connector from the throttle body.
- Remove the throttle body mounting bolts with the appropriate socket.
- Gently pull the throttle body away from the intake manifold.
Clean the Throttle Body:
- Use throttle body cleaner and a soft brush to clean the throttle plate and walls.
- Ensure that no debris falls into the intake manifold during cleaning.
- Wipe clean with a lint-free cloth.
Reinstall the Throttle Body:
- Place a new gasket on the intake manifold (if applicable).
- Reattach the throttle body, securing it with bolts to the specified torque (typically 14-18 ft-lbs).
- Reconnect the electrical connector and air intake duct.

3. Test and Replace Throttle Position Sensor (if necessary)

Test the TPS:
- Reconnect the battery and set your multimeter to measure voltage.
- Connect the multimeter leads to the TPS terminals and slowly move the throttle pedal.
- Check for a smooth increase in voltage; if it jumps or is inconsistent, the TPS may need replacement.
Replace the TPS:
- If faulty, remove the TPS from the throttle body by unscrewing it.
- Install the new TPS, ensuring it is properly aligned and secured.
- Reconnect any wiring harnesses.
