Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Repair Exhaust System

Lift the Vehicle: Use a hydraulic lift or jack stands to elevate the vehicle safely.
Inspect for Leaks: Examine the exhaust manifold, catalytic converter, and exhaust pipes for cracks or holes.
Repair or Replace:
- If a leak is found, use exhaust repair tape for small cracks or replace the affected section for larger damages.
- Ensure all connections are tight and secure.

3. Check and Replace Spark Plugs

Remove Ignition Coils: Unscrew and remove the ignition coils from the spark plugs.
Remove Spark Plugs: Use a socket wrench to take out the spark plugs.
Inspect for Damage: Check the spark plugs for wear, such as carbon build-up or damaged electrodes.
Replace: Install new spark plugs according to manufacturer specifications (check gap settings).
Reattach Ignition Coils: Secure the ignition coils back in place.

4. Inspect and Replace Components (if necessary)

Check Engine Mounts: Inspect engine mounts for cracks or excessive wear.
Replace as Needed: If damaged, remove bolts securing the engine mount and replace with a new mount.

5. Final Assembly

Reconnect the battery.
Lower the vehicle back to the ground.
