Solution

1. Preparation

Tools Required: Socket set, screwdriver set, throttle body cleaner, soft cloths, safety goggles, gloves.
Safety Warnings: Disconnect the negative battery terminal to prevent electrical shorts. Allow the engine to cool before starting work.

2. Remove Air Intake Duct

Locate the air intake duct connected to the throttle body.
Use a socket or screwdriver to loosen and remove any clamps or screws securing the duct.
Carefully detach the duct from the throttle body and set it aside.

3. Remove Throttle Body

Disconnect the electrical connector from the throttle body.
Remove any bolts securing the throttle body to the intake manifold using the socket set.
Gently pull the throttle body away from the intake manifold. Be cautious of any gasket that may stick to the throttle body or intake manifold; replace if damaged.

4. Clean Throttle Body

Spray throttle body cleaner generously onto a soft cloth or directly into the throttle body.
Use the cloth to wipe down the interior surfaces, focusing on the throttle plate and surrounding areas to remove carbon deposits.
Open the throttle plate manually (if necessary) to clean behind it thoroughly.
Ensure no cleaner residue remains, and the surfaces are clean and dry.

5. Reinstall Throttle Body

Position the throttle body back onto the intake manifold, ensuring that the gasket is in place.
Tighten the bolts to the manufacturer's torque specifications (typically around 89-106 in-lbs, but verify in the service manual).
Reconnect the electrical connector to the throttle body.

6. Reattach Air Intake Duct

Position the air intake duct back onto the throttle body.
Secure it using the clamps or screws previously removed.
Ensure all connections are tight and secure.

7. Final Checks

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes to ensure proper operation.
