Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Fuel Filter

Locate the fuel filter (usually along the fuel line).
Use a wrench to disconnect the fuel lines from the filter (be cautious about fuel spillage).
Remove the old fuel filter and install a new one, ensuring the direction of flow is correct.
Reconnect the fuel lines securely and check for leaks.

3. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle body interior.
Ensure the throttle plate opens and closes freely.
Reattach the air intake duct securely.

4. Replace Spark Plugs and Ignition Coils

Remove the engine cover if necessary to access the spark plugs.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils using a socket wrench.
Replace the spark plugs with OEM specifications, ensuring proper gap.
Reinstall the ignition coils and reconnect the electrical connectors.

5. Check and Clean the Mass Air Flow Sensor (if applicable)

Locate the mass air flow (MAF) sensor in the air intake system.
Remove the MAF sensor carefully.
Clean the sensor with MAF cleaner spray, avoiding contact with the sensor element.
Reinstall the MAF sensor securely.
