Solution

1. Preparation

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

2. Check and Replace Air Filter

Remove the air filter housing cover using a socket set.
Inspect the air filter for dirt and debris; replace it if necessary.
Reassemble the air filter housing and ensure it is sealed properly.

3. Inspect and Replace Spark Plugs

Remove ignition coil covers if necessary 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 spark plugs for wear; replace with OEM specifications if needed (typically NGK or Denso).
Reinstall the ignition coils and reconnect electrical connectors.

4. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and body.
Ensure that there is no residue left and the throttle plate moves freely.
Reattach the air intake duct securely.

5. Check and Replace Fuel Filter

Locate the fuel filter along the fuel line (check manual for exact location).
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines from the filter using appropriate line wrenches.
Replace the old filter with a new one, ensuring proper orientation and secure connections.
