Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid electrical issues.

2. Replace Air Filter

Remove the air filter housing cover by unscrewing or unclipping it.
Take out the old air filter and inspect the housing for dirt.
Install a new air filter, ensuring it fits securely.
Reattach the air filter housing cover.

3. Check and Replace Spark Plugs

Remove the ignition coil by unscrewing it from the engine.
Disconnect the electrical connector from the ignition coil.
Remove the old spark plug using a spark plug socket.
Inspect the old spark plug for wear; replace if necessary with OEM specifications.
Install the new spark plug and torque it to manufacturer specifications (typically around 13 lb-ft).
Reinstall the ignition coil.

4. Inspect and Replace Fuel Filter (if applicable)

Locate the fuel filter (may vary by engine type).
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines carefully.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect fuel lines and reinstall the fuel pump fuse.

5. Verify Ignition System

Test ignition coils with a multimeter to ensure they are within specifications (consult service manual for details).
Replace any faulty ignition coils.
