Solution

1. Preparation

Tools Required:
- Flathead screwdriver
- Torx screwdriver set
- Clean rags
- Throttle body cleaner
- Safety goggles

Disconnect the negative battery terminal to prevent any electrical shorts.

2. Remove Engine Cover

Unscrew any bolts or screws securing the engine cover using a Torx screwdriver.
Carefully lift off the engine cover and set it aside.

3. Access Throttle Body

Locate the throttle body on the intake manifold.
Disconnect the air intake duct by loosening the clamps with a flathead screwdriver and gently pulling it away from the throttle body.
If necessary, disconnect any electrical connectors attached to the throttle body by pressing the release tab and pulling them out.

4. Clean Throttle Body

Spray throttle body cleaner directly onto a clean rag and wipe the internal surfaces of the throttle body, including the throttle plate and walls.
Use a soft brush if needed to scrub away stubborn carbon deposits without scratching the surface.
Ensure that the throttle plate can move freely and does not stick.

5. Reassemble Components

Reconnect any electrical connectors you previously removed.
Reattach the air intake duct, ensuring it is securely fastened with clamps.
Place the engine cover back on and secure it with the screws or bolts removed earlier.
Reconnect the negative battery terminal.
