Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Allow the engine to cool down completely before starting the cleaning process.

2. Remove Engine Cover

Use a socket set to remove the screws securing the engine cover.
Carefully lift off the engine cover and set it aside.

3. Access Throttle Body

Locate the throttle body, typically connected to the intake manifold.
Disconnect the electrical connector from the throttle body by pressing the release tab and pulling it off.
Loosen the clamps securing the intake duct to the throttle body using a screwdriver or socket.
Remove the intake duct from the throttle body.

4. Clean the Throttle Body

Use a throttle body cleaner specifically designed for automotive use.
Spray the cleaner onto a clean, lint-free cloth or directly onto the throttle body.
Gently wipe the inside of the throttle body, paying close attention to the throttle plate and walls.
Open the throttle plate (using your hand or a suitable tool) to clean behind it.
Make sure to remove all carbon deposits and dirt without leaving any residue.

5. Reassemble Components

Reattach the intake duct to the throttle body and secure it with the clamps.
Connect the electrical connector back to the throttle body.
Place the engine cover back on and secure it with screws.

6. Final Checks

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