Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to prevent electrical shorts or shocks.
Allow engine to cool before beginning work.

2. Inspect and Clean Throttle Body

Remove the air intake duct:
- Loosen the clamps securing the duct to the throttle body using a screwdriver.
- Remove the duct carefully to access the throttle body.
Clean the throttle body:
- Use throttle body cleaner and a soft cloth to remove carbon deposits on the throttle plate and inside the throttle body.
- Ensure the throttle plate moves freely after cleaning.

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

Remove the throttle position sensor:
- Disconnect the electrical connector from the throttle position sensor.
- Remove the screws securing the sensor to the throttle body with a socket set.
Install the new throttle position sensor:
- Position the new sensor and secure it with screws (torque to manufacturer's specifications).
- Reconnect the electrical connector.

4. Reassemble and Test

Reattach the air intake duct and secure it with clamps.
Reconnect the battery.
Start the engine and allow it to idle to ensure the throttle operates smoothly.
