Solution

1. Preparation

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

2. Replace Spark Plugs

Remove the ignition coils by unscrewing the retaining bolts and disconnecting the electrical connectors.
Use a spark plug socket to remove the old spark plugs.
Inspect the old plugs for signs of fouling or damage.
Install new spark plugs, tightening to the manufacturer’s specified torque (typically around 15-20 Nm).
Reinstall ignition coils and reconnect electrical connectors.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter, which may be integrated into the fuel pump assembly.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using line removal tools, taking care to capture any spilled fuel.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and reinstall the fuel pump fuse.

4. Inspect and Clean Air Intake

Remove the air intake duct from the throttle body.
Inspect the air filter for dirt or blockage; replace if necessary.
Clean the throttle body with throttle body cleaner and a soft cloth.
Reinstall the air intake duct securely.

5. Inspect Engine Mounts

Visually inspect engine mounts for cracks or separation.
If damaged, use appropriate tools to remove the old mounts and install new ones, following torque specifications.
