Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, vacuum gauge, fuel pressure gauge, and basic hand tools.
Ensure the vehicle is in a safe and flat location, and the engine is cool.
Disconnect the battery before starting work to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Use a socket set to remove the bolts securing the engine mounts to the engine and frame.
- Carefully inspect the mounts for cracks, splits, or excessive wear.
- Replace any damaged mounts with new OEM or quality aftermarket mounts.
- Reinstall the bolts and torque them to the manufacturer's specifications (consult service manual for exact torque values).

3. Check and Replace Spark Plugs

Sub-steps:
- Remove the engine cover if applicable using a socket set.
- Use a spark plug socket to remove each spark plug; inspect for signs of wear or carbon buildup.
- Replace with new spark plugs that meet OEM specifications, ensuring proper gap.
- Reinstall the spark plug wires or ignition coils.

4. Address Vacuum Leaks

Sub-steps:
- Visually inspect all vacuum hoses for cracks or disconnections.
- Use a vacuum gauge to test the intake manifold for leaks.
- Replace any damaged hoses and ensure all connections are secure.

5. Test Fuel Injectors

Sub-steps:
- Connect a fuel pressure gauge to the fuel rail to check for proper fuel pressure (consult service manual for specifications).
- If pressure is low, inspect fuel filter and pump.
- Perform injector cleaning or replacement if they are clogged or malfunctioning.
