Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Engine Mounts

Use a jack to lift the engine slightly and relieve pressure on the mounts.
Visually inspect engine mounts for cracks, separation, or significant wear.
Replace any damaged engine mounts with new OEM parts.

3. Check for Vacuum Leaks

Use a smoke machine or carburetor cleaner to check for leaks in vacuum lines.
Replace any damaged or cracked hoses identified during the inspection.

4. Inspect the Ignition System

Remove and inspect spark plugs for wear, fouling, or improper gaps.
Replace spark plugs if they are worn or damaged; torque to manufacturer specifications.
Test ignition coils for proper resistance and replace if faulty.

5. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position without starting the engine and check the pressure.
If pressure is below specifications, check the fuel pump and replace if necessary.

6. Perform a Compression Test

Remove spark plugs and insert the compression tester into each cylinder.
Crank the engine and record the compression readings.
Compare readings to manufacturer specifications; replace any faulty components as necessary.
