Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety during work.
Allow the engine to cool before proceeding with repairs.

2. Inspect and Clean Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt.
If dirty, clean it with compressed air or replace it with a new filter.
Reinstall the air filter and housing cover securely.

3. Check and Replace Fuel Filter (if needed)

Locate the fuel filter; it may be integrated with the fuel pump in the tank.
If an external fuel filter is present, use a wrench to disconnect the fuel lines.
Replace the fuel filter with a new one and ensure all connections are secure.

4. Clean Throttle Body

Remove the intake duct leading to the throttle body.
Use throttle body cleaner and a soft cloth to remove carbon deposits.
Reattach the intake duct and ensure all clamps are tightened.

5. Inspect and Replace Spark Plugs/Coils (if necessary)

Remove the ignition coil cover using a socket set.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils and spark plugs using a spark plug socket.
Inspect for wear and replace with new spark plugs if necessary.
Reinstall the ignition coils and cover, ensuring all connections are secure.

6. Final Checks

Reconnect the battery.
Start the engine and check for any warning lights or irregularities.
