Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the exhaust system from the exhaust manifold to the tailpipe.
3. Look for any visible cracks, rust, or loose connections.
4. Use a flashlight to check for leaks or damaged hangers.
Tools Required: Jack, jack stands, flashlight.

3. Check Ignition Components

Sub-steps:
1. Remove the engine cover if applicable.
2. Inspect the spark plugs for wear, carbon buildup, or damage; replace if necessary.
3. Test the ignition coils using a multimeter to ensure they are functioning correctly.
4. Reinstall components securely.
Tools Required: Socket set, multimeter.

4. Repair or Replace Faulty Components

Sub-steps:
1. If any faulty components are found (e.g., cracked exhaust manifold, damaged spark plugs), replace them with OEM parts.
2. Tighten any loose connections in the exhaust or intake system.
