Solution

1. Preparation

Tools Required:
- Flathead screwdriver
- Torx socket set
- Cleaning brush or cloth
- Throttle body cleaner
- Safety goggles
- Gloves
Safety Warnings:
- Disconnect the battery before starting to prevent electrical issues.
- Allow the engine to cool before working on the throttle body.

2. Remove Engine Cover

Locate and remove the screws or bolts securing the engine cover using the Torx socket.
Carefully lift off the engine cover and set it aside.

3. Disconnect Throttle Body

Disconnect the electrical connector from the throttle body by pressing the release tab and pulling it away.
Loosen the hose clamps securing the intake duct to the throttle body using a flathead screwdriver, then remove the duct.
Remove the bolts securing the throttle body to the intake manifold using the Torx socket.

4. Clean Throttle Body

Spray throttle body cleaner onto a cloth or directly into the throttle body opening (do not spray into the air intake).
Use the cleaning brush to gently scrub the inside of the throttle body to remove carbon buildup.
Wipe clean with a lint-free cloth to ensure that no residue remains.

5. Reinstall Throttle Body

Position the throttle body back onto the intake manifold and secure it using the previously removed bolts. Tighten to the manufacturer’s torque specifications (typically around 8-10 Nm).
Reconnect the electrical connector to the throttle body.
Reattach the intake duct and secure it with the hose clamps.

6. Reinstall Engine Cover

Place the engine cover back on and secure it with the screws or bolts.

7. Reconnect Battery

Reconnect the negative terminal of the battery.
