Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Lift the vehicle securely using a jack and place jack stands.
2. Remove any components obstructing access to the engine mounts (if necessary).
3. Using a socket set, remove the bolts securing the damaged engine mounts.
4. Replace with new engine mounts, ensuring proper alignment.
5. Torque the bolts to the manufacturer’s specifications (usually around 40-50 ft-lbs, check service manual for exact values).

3. Replace Spark Plugs

Sub-steps:
1. Locate the ignition coil connectors and disconnect them.
2. Remove the ignition coils using a socket set.
3. Remove old spark plugs with a spark plug socket.
4. Check the gap on new spark plugs using a gap tool and adjust if necessary.
5. Install new spark plugs and torque to the manufacturer’s specifications (typically around 13 ft-lbs).
6. Reinstall ignition coils and reconnect connectors.

4. Clean or Replace Fuel Injectors

Sub-steps:
1. Remove the air intake duct to access the fuel rail.
2. Disconnect fuel lines and carefully relieve fuel pressure using a rag to catch any spills.
3. Remove fuel injectors from the fuel rail.
4. Clean injectors using a specialized injector cleaning kit or replace them if necessary.
5. Reinstall fuel injectors and reconnect lines ensuring no leaks.
