Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge, and basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Worn Engine Mounts

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the engine cover if necessary for access.
3. Locate the engine mounts and inspect them for cracks or excessive wear.
4. Remove the bolts securing the damaged engine mount using a socket wrench.
5. Install the new engine mount in the same location, ensuring proper alignment.
6. Torque the bolts to the manufacturer's specifications (usually around 40-60 ft-lbs, but consult the service manual).
7. Reinstall the engine cover.

3. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil cover if applicable to access the spark plugs.
2. Disconnect the ignition coil connectors and remove the coils using a socket set.
3. Use a spark plug socket to remove the old spark plugs.
4. Inspect the spark plugs for wear; replace with new plugs if necessary (follow specifications for gap and type).
5. Reinstall the ignition coils and connector.

4. Clean or Replace Fuel Injectors

Sub-steps:
1. Remove the fuel rail to access fuel injectors, ensuring the fuel system is depressurized first.
2. Inspect each injector for clogs or leaks.
3. Clean injectors using a professional cleaning tool or replace them if they are faulty.
4. Reinstall the fuel rail and ensure all connections are secure.
