Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, vacuum gauge, multimeter, cleaning supplies.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect Engine Mounts

Visually examine all engine mounts for cracks, tears, or signs of excessive wear.
Using a pry bar, gently lift the engine to check for excessive movement in the mounts.
If damaged, remove the old mounts using a socket set and replace them with new mounts, ensuring to torque them to the manufacturer's specifications.

3. Address Spark Plugs and Ignition System

Remove the spark plug wires or ignition coils (if applicable) using a socket set.
Inspect the spark plugs for wear; replace if they show signs of fouling or excessive wear.
Reinstall the new or cleaned spark plugs and reattach the ignition components, ensuring all connections are secure.

4. Inspect and Clean Throttle Body

Remove the air intake duct leading to the throttle body using a socket set.
Use throttle body cleaner and a soft cloth to clean the throttle body, removing any carbon buildup.
Reattach the air intake duct securely and ensure all clamps are tightened.

5. Check for Vacuum Leaks

Using a vacuum gauge, connect it to a vacuum source and check for adequate vacuum levels at idle.
Listen for hissing sounds around hoses and connections that may indicate leaks.
Replace any damaged vacuum hoses and ensure all connections are tight.
