Solution

1. Preparation

Gather tools and parts required for diagnostics and potential repair.
Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Inspect and Replace Engine Mounts

Lift the vehicle using a jack and secure it on jack stands.
Remove any components obstructing access to the engine mounts (e.g., air intake duct).
Inspect each engine mount for cracks, excessive wear, or fluid leaks.
If necessary, remove the bolts securing the damaged engine mount using a socket wrench.
Replace the engine mount with a new part, ensuring it is properly aligned.
Tighten the bolts to the manufacturer's specified torque settings.

3. Check and Replace Ignition Components

Remove the engine cover if necessary to access ignition components.
Inspect spark plugs for wear, carbon buildup, or damage. Replace if needed.
Test ignition coils with a multimeter to ensure they are functioning properly; replace any faulty coils.
Reassemble any components removed during the inspection.

4. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Start the engine and monitor the fuel pressure; compare with manufacturer specifications.
If the fuel pressure is low, check the fuel pump and fuel filter for issues.
Replace the fuel filter if clogged and the fuel pump if it is not delivering adequate pressure.
