Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, cleaning brush, lint-free cloth, throttle body cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Air Intake Hose

Use the socket set to loosen the clamps securing the air intake hose to the throttle body.
Carefully detach the air intake hose from the throttle body, taking care not to damage any sensors or wiring.

3. Access Throttle Body

If needed, remove any additional components obstructing access to the throttle body, such as the engine cover or throttle body wiring harness.
Ensure all connectors and hoses are labeled for reinstallation.

4. Clean Throttle Body

Spray throttle body cleaner onto a lint-free cloth or directly into the throttle body, avoiding excessive overspray.
Use the cleaning brush to gently scrub the inner surfaces of the throttle body, focusing on areas with heavy carbon buildup.
Wipe down all surfaces with the cloth until clean, ensuring no residue is left behind.

5. Reassemble Components

Reattach the air intake hose, ensuring it is secured tightly with the clamps.
Reconnect any wiring harnesses or components that were removed.
Reconnect the negative battery terminal.

6. Final Inspection

Start the engine and allow it to reach operating temperature.
Check for any abnormal sounds or idle fluctuations, and ensure all components are secure.
