Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electronic components.
Allow the engine to cool if it has been running.

2. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner onto a soft cloth and wipe the inside of the throttle body to remove carbon deposits.
Ensure the throttle plate can move freely and does not stick.
Reassemble the air intake duct securely.

3. Throttle Position Sensor Replacement (if necessary)

Tools Required: Socket set, torque wrench, multimeter.
Disconnect the wiring harness from the throttle position sensor.
Remove the sensor from the throttle body using the appropriate socket.
Install the new throttle position sensor, ensuring it is properly aligned.
Torque the sensor to manufacturer specifications (consult service manual for exact value).
Reconnect the wiring harness.

4. Testing and Calibration
