Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, visual inspection tools (flashlight, mirror).
Ensure the vehicle is parked on a flat surface, and the engine is cool.

2. Inspect Exhaust System

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the exhaust pipes, muffler, and catalytic converter for any cracks, holes, or loose fittings.
3. Tighten any loose bolts or connections in the exhaust system.
4. If any damage is found, replace the damaged components with OEM parts.

3. Check Intake System

Sub-steps:
1. Open the hood and locate the air intake assembly.
2. Remove the air filter and inspect it for dirt or damage; replace if necessary.
3. Inspect the intake hoses for cracks or looseness; replace if damaged.
4. Reassemble the intake system securely.

4. Examine Engine Mounts

Sub-steps:
1. Inspect engine mounts for signs of wear, such as cracks or excessive movement.
2. If any mounts are damaged, use a socket set to remove the old mounts and replace them with new OEM mounts.
3. Torque the new mounts to the manufacturer specifications.
