Solution

1. Preparation

Tools Required: Socket set, screwdriver set, throttle body cleaner, lint-free cloths, safety glasses, gloves.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Allow the engine to cool down completely.

2. Remove the Air Intake Hose

Tools Required: Flathead screwdriver or socket set.
Loosen the clamps securing the air intake hose to the throttle body.
Carefully detach the hose from the throttle body and set it aside.

3. Remove the Throttle Body

Tools Required: Socket set.
Disconnect the electrical connector from the throttle body.
Remove any bolts securing the throttle body to the intake manifold. Note the torque values for reinstallation.
Gently pull the throttle body away from the intake manifold. Be cautious of any gasket that may need replacement.

4. Clean the Throttle Body

Spray throttle body cleaner onto a lint-free cloth.
Wipe the inside of the throttle body, focusing on the throttle plate and the walls, removing any carbon buildup.
Open the throttle plate manually (if necessary) to clean the interior surfaces thoroughly.
Ensure no cleaner residue remains inside the throttle body.

5. Reinstall the Throttle Body

Place a new gasket (if applicable) onto the intake manifold.
Align the throttle body and secure it with the bolts, tightening to the manufacturer’s specified torque values.
Reconnect the electrical connector to the throttle body.
