Solution

1. Preparation

Gather tools and necessary parts.
Ensure the vehicle is parked on a flat surface, and the engine is cool.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, spark plug socket, torque wrench.
Remove the engine cover if applicable.
Disconnect the ignition coil connectors and remove the coils.
Use a spark plug socket to remove the spark plugs.
Inspect the plugs for wear; replace if necessary with OEM-spec plugs.
Torque the new spark plugs to the manufacturer-recommended specification (usually around 13-15 lb-ft).
Reinstall the ignition coils and connectors.

3. Check and Replace Engine Mounts (if necessary)

Tools Required: Socket set, jack stands, hydraulic jack.
Lift the vehicle using the hydraulic jack and secure it with jack stands.
Inspect the engine mounts for cracks or separation.
If damaged, remove the bolts securing the engine mount to the frame and engine.
Install the new engine mount and torque the bolts to the manufacturer's specifications.
Lower the vehicle and remove the jack stands.

4. Fuel System Inspection and Cleaning

Tools Required: Fuel pressure gauge, fuel injector cleaner.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "on" position (do not start) and check for proper fuel pressure.
If pressure is below specifications, inspect the fuel pump and filter.
Consider using a fuel injector cleaner to clean the injectors if they are clogged.
