Solution

1. Preparation

Tools Required:
- Socket set
- Screwdriver set
- Throttle body cleaner
- Clean microfiber cloths
- Safety glasses
- Gloves
Ensure the engine is cool and disconnect the negative battery terminal to prevent electrical shorts.

2. Remove the Air Intake Duct

Loosen the clamps securing the air intake duct to the throttle body.
Disconnect any electrical connectors attached to the duct.
Carefully remove the duct and set it aside.

3. Access the Throttle Body

Identify and remove the screws or bolts securing the throttle body to the intake manifold using the socket set.
Disconnect any electrical connectors attached to the throttle body; ensure to note their positions for reinstallation.

4. Clean the Throttle Body

Spray throttle body cleaner directly onto the throttle plate and surrounding area.
Use a clean microfiber cloth to gently scrub away carbon buildup, being cautious not to damage the throttle plate.
Open the throttle plate manually (if allowed) to clean the interior surfaces thoroughly.
Wipe away any excess cleaner and residue with a clean cloth.

5. Reassemble Components

Reinstall the throttle body by reversing the removal steps. Ensure all bolts are tightened to the manufacturer's specifications (usually around 10-15 Nm).
Reconnect any electrical connectors and ensure they are secure.
Reattach the air intake duct and tighten the clamps.

6. Final Steps

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes to let the ECU recalibrate. Check for any warning lights on the dashboard.
