Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Sub-steps:
1. Locate the engine mounts, typically found on the front, rear, and sides of the engine.
2. Use the pry bar to check for excessive movement or wear on mounts.
3. Remove the bolts securing the damaged engine mount using the socket set.
4. Replace with a new mount, ensuring proper alignment.
5. Torque the bolts to the manufacturer's specifications (refer to service manual for exact torque values).

3. Check and Replace Spark Plugs/Ignition Coils

Tools Required: Spark plug socket, ratchet, torque wrench
Sub-steps:
1. Remove the engine cover if necessary.
2. Unplug the ignition coil connectors and remove the coils.
3. Extract the spark plugs using the spark plug socket.
4. Inspect the spark plugs for wear or damage; replace if necessary.
5. Install new spark plugs with the correct gap setting and torque to specification.
6. Reinstall the ignition coils and reconnect the connectors.

4. Inspect Fuel Injectors

Tools Required: Fuel pressure gauge, injector cleaner
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail to check for proper fuel pressure.
2. If pressure is low, check the fuel pump and filter.
3. Use injector cleaner to clean the fuel injectors if they are clogged.
4. Replace any faulty fuel injectors as needed.
