Solution

1. Preparation

Tools Required: Socket set, torque wrench, vacuum cleaner or compressed air, soft brushes, scrapers, shop towels.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool down completely before starting the work.

2. Remove Intake Components

Remove the engine cover by unscrewing the fasteners.
Disconnect the air intake duct from the throttle body.
Remove the throttle body by unscrewing it from the intake manifold.
Take off the intake manifold by removing all necessary bolts and connectors.

3. Clean Carbon Buildup

Use a carbon cleaning solution specifically designed for intake systems. Apply it generously to the affected areas of the intake manifold and valves.
Scrape off heavy carbon deposits using a soft scraper or brush carefully to avoid damaging surfaces.
Use a shop vacuum or compressed air to remove loose carbon particles.
Wipe down all surfaces with shop towels to ensure they are clean and free of debris.

4. Reassemble Components

Reinstall the intake manifold by securing it with the appropriate torque settings as specified in the service manual.
Reattach the throttle body to the intake manifold and reconnect all electrical connectors.
Reconnect the air intake duct to the throttle body.
Secure the engine cover back in place.

5. Final Checks

Reconnect the battery.
