Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean Throttle Body

Remove the air intake duct connected to the throttle body. Use a socket set for any clamps.
Spray throttle body cleaner onto a clean cloth and wipe the throttle body interior, including the butterfly valve, until free of carbon deposits.
Reinstall the air intake duct and reconnect the battery.

3. Check and Replace Fuel Filter

Locate the fuel filter; refer to the vehicle's service manual for exact location.
Use a wrench to disconnect the inlet and outlet fuel lines. Be cautious of fuel spillage.
Remove the old fuel filter and install the new one, ensuring correct orientation.
Reconnect fuel lines securely and check for leaks.

4. Inspect and Replace Spark Plugs

Remove the ignition coil by unbolting it and disconnecting the electrical connector.
Use a spark plug socket to remove the old spark plugs.
Inspect the old plugs for wear; replace them with new ones, ensuring they are gapped correctly as per manufacturer specifications.
Reinstall the ignition coils and reconnect the electrical connectors.
