Solution

1. Preparation

Disconnect the battery to ensure safety while working on electrical components.
Gather tools and parts required for the repair.

2. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and the interior of the throttle body.
Reinstall the air intake duct securely.

3. Inspect and Replace Accelerator Pedal Position Sensor (if necessary)

Locate the accelerator pedal position sensor mounted on the pedal assembly.
Disconnect the electrical connector from the sensor.
Remove the mounting screws securing the sensor and take it out.
Install the new accelerator pedal position sensor and secure it with screws.
Reconnect the electrical connector.

4. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter in the fuel line (refer to the service manual for exact location).
Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter, noting the orientation of the flow.
Replace the old fuel filter with a new one, ensuring proper flow direction.
Reconnect the fuel lines and reinstall the fuel pump fuse.

5. Reconnect Battery

Reconnect the negative terminal of the battery.
Start the engine and allow it to idle.
