Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to reset the electronic control unit (ECU).

2. Throttle Body Cleaning (if applicable)

Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner onto the throttle plate and wipe clean with a soft cloth.
Reinstall the air intake duct securely.

3. Throttle Reset Procedure

Tools Required: OBD-II scanner (if required).
Reconnect the negative battery terminal.
Sit in the driver's seat and turn the ignition key to the "ON" position without starting the engine.
Wait for about 10 seconds to allow the throttle to reset.
Start the engine and let it idle for 10 minutes to allow the ECU to relearn the throttle positions.
During idling, observe the throttle response by gently pressing the accelerator pedal several times.
