Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, vacuum gauge, fuel pressure gauge
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery cable to avoid electrical shorts.

2. Inspect Engine Mounts

Sub-steps:
- Locate the engine mounts (usually at the front and rear of the engine).
- Visually inspect for cracks, wear, or separation.
- Use a floor jack to lift the engine slightly and check for excessive movement in the mounts.
Replacement: If damaged, replace with OEM parts and torque to manufacturer's specifications.

3. Check for Vacuum Leaks

Sub-steps:
- Use a vacuum gauge to check the intake manifold vacuum.
- Inspect hoses connected to the intake for cracks or disconnections.
- Spray carburetor cleaner around the intake area and listen for changes in engine RPM to identify leaks.

4. Inspect and Replace Spark Plugs

Sub-steps:
- Remove the spark plug wires and unscrew the spark plugs using a socket wrench.
- Inspect plugs for wear, carbon build-up, or damage.
- Replace with OEM specifications and torque to proper values (typically 13-15 lb-ft).

5. Test Fuel Pressure

Sub-steps:
- Connect the fuel pressure gauge to the fuel rail.
- Turn the ignition key to the ON position (do not start the engine) and check the pressure reading against manufacturer specifications.
- If the pressure is low, inspect the fuel pump and filter for issues.

6. Inspect Ignition System

Sub-steps:
- Check the ignition coils for damage and ensure they are securely connected.
- Inspect plug wires for cracks or poor connections.
- Replace any faulty components with OEM parts.
