Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shock or accidental short circuits.
Ensure the vehicle is on a flat surface and securely supported.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body (use appropriate socket set).
Use throttle body cleaner and a soft cloth or brush to clean the throttle plate and surrounding areas.
Ensure no debris falls into the intake manifold during cleaning.
Reattach the air intake duct securely.

3. Check and Replace Throttle Position Sensor (if needed)

Disconnect the electrical connector from the throttle position sensor.
Remove the sensor using the appropriate socket or screwdriver.
Install the new throttle position sensor, ensuring it's properly seated.
Reconnect the electrical connector firmly.

4. Inspect and Adjust the Accelerator Cable (if applicable)

Locate the accelerator cable and inspect for any fraying or damage.
If damaged, remove the old cable and install a new one.
Adjust the cable tension according to the manufacturer's specifications to ensure smooth operation.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the engine and allow it to idle.
Test the throttle by pressing the accelerator pedal to ensure it operates smoothly.
