Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to prevent electrical shorts during repair.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts (typically two on the front and one on the rear).
3. Use the socket set to remove the bolts securing the damaged engine mount.
4. Use the pry bar to gently lift the engine and remove the old mount.
5. Position the new engine mount in place and secure it with bolts, tightening them to the manufacturer's specified torque.

3. Address Vacuum Leaks

Tools Required: Vacuum gauge, hose clamp pliers
Sub-steps:
1. Start the engine and use the vacuum gauge to check for proper vacuum levels.
2. Inspect all hoses for cracks, loose connections, or disconnections.
3. Replace any damaged hoses and secure them with hose clamps as necessary.

4. Inspect and Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench
Sub-steps:
1. Remove the ignition coils to access the spark plugs.
2. Use the spark plug socket to remove the old spark plugs.
3. Inspect the old plugs for wear; replace them with new ones if necessary.
4. Install the new spark plugs and torque them to the manufacturer's specified value.
5. Reinstall the ignition coils.

5. Fuel System Check

Tools Required: Fuel pressure gauge, basic hand tools
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Start the engine and check for proper fuel pressure according to specifications.
3. If pressure is low, inspect the fuel filter and fuel pump for malfunctions and replace if needed.
