Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Engine Mounts

Tools Required: Socket set, pry bar
Inspect each engine mount for cracks or separation.
Use a pry bar to gently lift the engine and check if the mounts allow for excessive movement.
If damaged, proceed to replace the engine mounts.

3. Replace Spark Plugs and Ignition Coils (if necessary)

Tools Required: Socket set, torque wrench, spark plug gap tool
Remove the ignition coil cover (if applicable).
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils and spark plugs using the socket set.
Install new spark plugs, ensuring they are gapped to the manufacturer’s specifications.
Reinstall ignition coils and reconnect electrical connectors.

4. Address Vacuum Leaks

Tools Required: Vacuum gauge, hose clamp pliers
Inspect all vacuum hoses for cracks or loose connections.
Replace any damaged hoses.
Use a vacuum gauge to test for proper vacuum levels, ensuring the engine is not running lean.

5. Check 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 to check the pressure.
If pressure is low, inspect the fuel pump and filter for replacement.
