Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts while working.

2. Inspect Engine Mounts

Tools Required: Socket set, torque wrench
Using the socket set, remove any components obstructing access to the engine mounts.
Visually inspect each engine mount for cracks, separation, or excessive wear.
If mounts are damaged, proceed to replace them.

3. Address Vacuum Leaks

Tools Required: Smoke machine (or alternative leak detection method)
Connect the smoke machine to the intake manifold.
Look for smoke escaping from any hoses or connections, indicating a vacuum leak.
Replace any damaged hoses or clamps as necessary.

4. Inspect Spark Plugs and Ignition Coils

Tools Required: Socket set, torque wrench
Remove the ignition coils by unscrewing them (if applicable) and gently pulling them out.
Remove the spark plugs using a spark plug socket and inspect for wear, carbon build-up, or damage.
Replace any faulty spark plugs and ignition coils with new ones, tightening to the manufacturer’s specifications.

5. Test Fuel Pressure

Tools Required: Fuel pressure gauge
Locate the fuel pressure test port on the fuel rail.
Connect the fuel pressure gauge and turn the ignition to the ON position (without starting the engine).
Check the pressure reading against the manufacturer’s specifications; replace the fuel pump or filter if needed.
