Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather necessary tools and parts.

2. Address Engine Mounts

Sub-steps:
- Use a socket set to remove the bolts securing the engine mounts.
- Lift the engine slightly using a jack with a block of wood to support it.
- Inspect the mounts for cracks, tears, or excessive wear.
- Replace damaged engine mounts with new ones, ensuring proper alignment.
- Torque the bolts to the manufacturer's specifications.

3. Replace Spark Plugs and Ignition Coils (if required)

Sub-steps:
- Disconnect the negative battery terminal.
- Remove the ignition coils using a socket set.
- Replace spark plugs with new ones, ensuring the gap is set according to specifications.
- Reinstall ignition coils and reconnect the battery terminal.

4. Inspect and Repair Vacuum Leaks

Sub-steps:
- Use a smoke machine to identify leaks in the intake manifold or vacuum hoses.
- Replace any damaged vacuum hoses or gaskets found during inspection.
- Ensure all connections are tight and secure.

5. Fuel System Check (if needed)

Sub-steps:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position (do not start) and check the fuel pressure.
- If pressure is below specifications, consider replacing the fuel filter or fuel pump.
