Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery to ensure safety during electrical work.

2. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body, removing any carbon deposits.
Reassemble the air intake duct securely.

3. Accelerator Pedal Position Sensor Check

Tools Required: Multimeter.
Locate the accelerator pedal position sensor, typically mounted on the pedal assembly.
Disconnect the sensor connector and use a multimeter to check for proper voltage output while pressing the accelerator pedal.
If the sensor is faulty, replace it with a new one.
