Solution

1. Preparation

Tools Required: Socket set, Torx screwdriver, throttle body cleaner, cleaning cloths, safety glasses, gloves
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool for safety.

2. Remove Air Intake Duct

Locate the air intake duct connected to the throttle body.
Use a socket set or Torx screwdriver to remove any clamps or screws securing the duct.
Gently pull the duct away from the throttle body, taking care not to damage any connections.

3. Access Throttle Body

Identify and remove any additional components that may obstruct access, such as the engine cover or brackets.
If applicable, disconnect any electrical connectors attached to the throttle body.

4. Clean Throttle Body

Spray throttle body cleaner directly onto the throttle plate and inside the throttle body.
Use a clean cloth or a soft brush to gently scrub the interior surfaces, focusing on the throttle plate and any carbon buildup.
Ensure the cleaner evaporates completely before reassembly.

5. Reassemble Components

Reconnect any electrical connectors and components removed during access.
Reattach the air intake duct, ensuring all clamps and screws are tightened securely.
Reconnect the negative battery terminal.
