Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to prevent electrical hazards.
Allow the engine to cool before starting work.

2. Inspect and Replace Engine Mounts

Lift the Vehicle: Use a hydraulic jack and jack stands to lift the front of the vehicle securely.
Remove Engine Mount Bolts: Use a socket set to remove the bolts holding the engine mounts to the frame and engine.
Inspect Mounts: Check for cracks, tears, or excessive wear. If damaged, proceed to replace.
Install New Engine Mounts: Position the new mounts and secure them with the bolts. Torque to manufacturer specifications (typically around 40-50 ft-lbs).
Lower the Vehicle: Carefully remove jack stands and lower the vehicle.

3. Check and Replace Spark Plugs

Remove Ignition Coils: Disconnect the electrical connectors and unscrew the ignition coils using a socket set.
Inspect Spark Plugs: Remove the spark plugs using a spark plug socket. Check for signs of wear or fouling.
Replace Spark Plugs: If worn, install new spark plugs, ensuring they are gapped correctly to manufacturer specifications (usually around 0.050 inches).
Reinstall Ignition Coils: Secure the ignition coils back into place and connect the electrical connectors.

4. Fuel System Inspection

Check Fuel Filter: Locate and inspect the fuel filter for clogs. Replace if necessary.
Inspect Fuel Injectors: Use a fuel injector cleaning kit to clean or replace injectors if they are found to be dirty or malfunctioning.
