Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Engine Mounts

Sub-steps:
1. Locate the engine mounts (usually located at the front and rear of the engine).
2. Use a socket set to remove any covers obstructing access.
3. Check for visible cracks, tears, or fluid leaks in the mounts.
4. Replace any damaged mounts with new ones, ensuring they are torqued to manufacturer specifications.

3. Check for Vacuum Leaks

Sub-steps:
1. With the engine running, use a vacuum gauge to check for consistent readings.
2. Inspect all vacuum hoses for cracks or disconnections.
3. Apply a smoke test if necessary to locate hard-to-find leaks.
4. Replace any damaged hoses and recheck vacuum levels.

4. Test Ignition System

Sub-steps:
1. Remove spark plug wires or coils using a socket set.
2. Inspect spark plugs for wear or carbon buildup; replace if necessary.
3. Use a multimeter to check the resistance of ignition coils.
4. Replace faulty coils or plugs as needed.

5. Examine Fuel Injectors

Sub-steps:
1. Remove fuel injector connectors.
2. Use a multimeter to check for proper resistance; replace if out of spec.
3. Clean fuel injectors using a professional cleaning kit or replace if clogged.
