Solution

1. Preparation

Gather tools and necessary parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Engine Mounts

Tools Required: Socket set, torque wrench
Sub-steps:
1. Locate the engine mounts; typically found on the front and rear of the engine.
2. Use a socket set to remove the bolts securing the engine mounts.
3. Inspect the mounts for cracks, tears, or excessive wear.
4. Replace any damaged mounts with new ones, torquing bolts to manufacturer specifications.

3. Check for Vacuum Leaks

Tools Required: Smoke machine or carburetor cleaner
Sub-steps:
1. With the engine running, carefully spray carburetor cleaner around the intake manifold and vacuum hoses.
2. Observe for any changes in idle speed, indicating a vacuum leak.
3. If a leak is found, replace the affected hoses or gasket.

4. Inspect Spark Plugs and Ignition Coils

Tools Required: Socket set, spark plug gap tool
Sub-steps:
1. Remove the ignition coils using a socket set.
2. Remove the spark plugs and inspect for signs of wear or fouling.
3. Replace spark plugs if necessary, ensuring proper gap settings.
4. Reinstall ignition coils and secure them properly.

5. Verify Fuel System

Tools Required: Fuel pressure gauge
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position without starting the engine and check the pressure.
3. Compare the reading to manufacturer specifications. If low, inspect the fuel pump and filter for issues.
