Solution

1. Preparation

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

2. Inspect and Replace Engine Mounts (if necessary)

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Locate the engine mounts and visually inspect for cracks or excessive wear.
3. Remove any components obstructing access to the mounts (e.g., air filter housing).
4. Use a socket set to remove the bolts securing the damaged mounts.
5. Install new engine mounts, ensuring proper alignment.
6. Torque the mount bolts to the manufacturer's specifications (consult service manual for specific torque values).

3. Check and Replace Spark Plugs (if necessary)

Sub-steps:
1. Remove the ignition coil or spark plug wires (note the order for reinstallation).
2. Use a spark plug socket to remove the spark plugs.
3. Inspect the spark plugs for wear or damage (replace if necessary).
4. Install new spark plugs, hand-tighten, then torque to the specified value (usually around 15-20 Nm).
5. Reconnect the ignition coils or spark plug wires securely.

4. Inspect and Replace Fuel Filter (if necessary)

Sub-steps:
1. Locate the fuel filter (typically near the fuel tank or along the fuel line).
2. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
3. Use appropriate tools to disconnect the fuel lines from the filter.
4. Install the new fuel filter, ensuring the flow direction matches the vehicle's markings.
5. Reconnect the fuel lines securely and restore the fuel pump fuse.
