Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Multimeter
Screwdrivers
Inspection mirror

2. Check and Replace Spark Plugs

Remove the ignition coil cover (if applicable) using a socket set.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils from the spark plugs.
Extract the spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace if they show signs of damage or excessive wear.
Install new spark plugs, ensuring they are gapped correctly according to manufacturer specifications (typically around 0.044 inches).
Reinstall ignition coils and connectors.

3. Inspect and Replace Engine Mounts

Visually inspect engine mounts for cracks, separation, or excessive wear.
Use a socket set to remove the bolts securing the engine mounts to the engine and the chassis.
Replace any damaged engine mounts with new ones, tightening the bolts to the manufacturer's specified torque (usually around 40-60 ft-lbs depending on the mount).
Recheck alignment and stability of the engine after installation.

4. Clean or Replace Air Filter

Open the engine cover to access the air intake system.
Remove the air filter housing cover using appropriate screwdrivers.
Take out the air filter and inspect for dirt and debris.
Clean the air filter (if reusable) or replace with a new one.
Reassemble the air intake system ensuring all clips and screws are secured.
