Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, torque wrench, flashlight, and safety glasses.
Ensure the vehicle is parked on a level surface with the engine off and the keys removed.

2. Inspect and Repair Exhaust System

Step 1: Lift the vehicle using a jack and secure it with jack stands.
Step 2: Visually inspect the exhaust system from the engine to the tailpipe for signs of damage or loose connections.
Step 3: Tighten any loose bolts or clamps found in the exhaust system.
Step 4: Replace any damaged components (e.g., gaskets, pipes, muffler) as necessary. Use the correct torque specifications when reassembling.

3. Address Engine and Intake Issues

Step 1: If error codes are present, refer to a repair manual for specific diagnostic procedures.
