Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, vacuum gauge, multimeter, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect Engine Mounts

Sub-steps:
1. Open the hood and visually inspect the engine mounts for cracks or separation.
2. Using a jack, support the engine slightly to relieve pressure on the mounts.
3. Remove fasteners securing the damaged mounts using a socket set.
4. Replace the damaged engine mounts with new ones, ensuring proper alignment.
5. Torque the fasteners to the manufacturer’s specifications (typically around 50-60 ft-lbs).

3. Check for Vacuum Leaks

Sub-steps:
1. Start the engine and let it idle.
2. Use a vacuum gauge to check for proper readings; anything below 18 inHg may indicate a leak.
3. Spray carburetor cleaner around intake hoses and gaskets while listening for changes in idle speed.
4. If a leak is found, replace the affected hoses or gaskets.

4. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the ignition coil connectors and unscrew the coils using a socket set.
2. Take out the old spark plugs using a spark plug socket.
3. Install new spark plugs (gapped to manufacturer specifications) and reattach the ignition coils.
4. Reconnect the ignition connectors.

5. Clean Fuel Injectors

Sub-steps:
1. Remove the fuel rail to access the injectors.
2. Clean the injectors with a dedicated fuel injector cleaner or ultrasonic cleaner.
3. Reinstall the injectors and fuel rail, ensuring proper sealing.
