Solution

1. Preparation

Gather tools including an OBD-II scanner, socket set, torque wrench, and vacuum gauge.
Ensure the vehicle is parked on a level surface and the engine is cool before starting.

2. Address Engine Mounts

Inspect Engine Mounts:
- Use a jack to support the engine.
- Visually inspect the engine mounts for cracks or separation.
Replace Damaged Engine Mounts:
- Remove the bolts securing the engine mount to the frame and engine.
- Install the new engine mount, ensuring proper alignment.
- Torque bolts to manufacturer specifications (usually around 40-50 lb-ft).

3. Check Spark Plugs and Ignition Coils

Remove Spark Plugs:
- Disconnect the ignition coils and use a socket to remove the spark plugs.
Inspect and Replace if Necessary:
- Check for wear or deposits on the spark plugs.
- Replace any damaged or worn spark plugs, ensuring to gap them according to specifications.
Install Ignition Coils:
- Reinstall coils and ensure connections are secure.

4. Inspect Fuel Injectors

Test Fuel Injectors:
- Use a fuel pressure gauge to check injector pressure.
- Disconnect and clean injectors if necessary, using a suitable injector cleaning kit.
Replace Faulty Injectors:
- If any injectors are defective, remove and replace with new ones, ensuring proper seating and connection.
