Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove the Air Intake Hose

Loosen the clamps securing the air intake hose to the throttle body using a flathead screwdriver.
Carefully detach the hose from the throttle body and set it aside.

3. Access the Throttle Body

Locate the throttle body mounted on the intake manifold.
If necessary, remove any electrical connectors or sensors attached to the throttle body, noting their positions for reinstallation.
Use the appropriate Torx screwdriver to remove the mounting bolts securing the throttle body.

4. Clean the Throttle Body

Remove the throttle body from the intake manifold.
Spray throttle body cleaner into the throttle body, focusing on the throttle plate and surrounding areas.
Use a lint-free cloth to wipe away carbon deposits carefully. Avoid using abrasive materials that can damage the surface.
Open the throttle plate manually to clean the inner surfaces thoroughly.

5. Reinstall the Throttle Body

Position the throttle body back onto the intake manifold and secure it with the mounting bolts. Use the manufacturer's torque specifications (typically around 7-10 Nm).
Reconnect any electrical connectors or sensors removed during disassembly.
