Solution

1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety during the repair.

2. Replace Worn Engine Mounts

Tools Required: Socket set, torque wrench, pry bar, jack stands
Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts (typically two at the front and one at the rear).
3. Using a socket set, remove the bolts securing the engine mounts to the engine and chassis.
4. Use a pry bar to gently remove the old engine mount from its position.
5. Install the new engine mount, ensuring it aligns properly.
6. Torque the bolts to manufacturer specifications (usually around 40-50 ft-lbs, consult the service manual for exact values).
7. Repeat for other mounts if necessary.

3. Replace Spark Plugs

Tools Required: Spark plug socket, ratchet, torque wrench
Sub-steps:
1. Remove the engine cover if necessary to access the spark plugs.
2. Disconnect the ignition coil connectors from the spark plugs.
3. Remove the ignition coils using a socket set.
4. Use a spark plug socket to remove the old spark plugs.
5. Inspect the old plugs for wear and replace them with new ones.
6. Torque the new spark plugs to the specified value (typically around 13-15 ft-lbs).
7. Reinstall the ignition coils and reconnect the connectors.

4. Check and Repair Fuel Delivery

Tools Required: Fuel pressure gauge, basic hand tools
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail according to the manufacturer's instructions.
2. Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure reading.
3. If the pressure is out of specification, inspect the fuel filter and fuel pump for issues.
4. Replace any faulty components as needed.
