Solution

1. Preparation

Gather tools and parts.
Disconnect the battery negative terminal to ensure safety.
Raise the vehicle if necessary for better access.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Visually inspect engine mounts for cracks or separation.
2. Use a torque wrench to remove the bolts securing the mounts.
3. Replace damaged mounts with new ones, ensuring proper alignment.
4. Torque bolts to manufacturer specifications (typically between 30-50 Nm, but refer to the service manual for specifics).

3. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil cover if applicable.
2. Disconnect ignition coils and remove them using a socket set.
3. Use a spark plug socket to remove old spark plugs.
4. Gap new spark plugs as per manufacturer specifications and install them.
5. Reinstall ignition coils and cover.

4. Check and Replace Ignition Coils

Sub-steps:
1. Test ignition coils with a multimeter to check for proper resistance.
2. If faulty, remove the coil connectors and bolts.
3. Replace with new ignition coils and reconnect.

5. Inspect Fuel System

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "On" position (without starting) and check the pressure.
3. If pressure is low, inspect the fuel pump and filter for issues.
4. Replace the fuel filter if necessary.
