Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to ensure safety when working on electrical components.

2. Inspect and Replace Spark Plugs

Remove the engine cover if applicable.
Use a socket set to remove the spark plug wires or ignition coils.
Remove the spark plugs using a spark plug socket.
Inspect the old spark plugs for wear or fouling. Replace with OEM-spec spark plugs if necessary.
Reinstall the spark plugs and reconnect the ignition coils or spark plug wires.

3. Check and Replace Engine Mounts

Using a jack, support the engine slightly to relieve pressure on the engine mounts.
Visually inspect the engine mounts for cracks or excessive wear.
If damaged, unbolt the engine mounts using a socket set and replace them with new ones.
Reinstall and torque the bolts to the manufacturer's specifications.

4. Inspect Air Intake and Fuel System

Check the air filter and replace it if clogged.
Inspect the intake manifold for any leaks and tighten any loose clamps.
If fuel injectors are suspected, clean or replace them according to manufacturer guidelines.
