Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to ensure safety during repairs.

2. Inspect and Repair Exhaust System

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect the entire exhaust system, including the headers, catalytic converter, and muffler for any visible cracks or holes.
3. Tighten any loose clamps or bolts found during inspection.
4. If damage is identified, replace the affected section of the exhaust using appropriate gaskets and hardware.
5. Reconnect the exhaust system components and torque bolts to manufacturer specifications.

3. Check and Replace Ignition Components

Sub-steps:
1. Remove engine covers if necessary to access spark plugs and ignition coils.
2. Inspect spark plugs for wear, carbon buildup, or damage; replace if necessary.
3. Test ignition coils with a multimeter according to manufacturer specifications; replace any faulty coils.
4. Reinstall spark plugs and ignition coils, ensuring proper torque settings are followed.

4. Clean or Replace Fuel Injectors

Sub-steps:
1. Remove the fuel rail to access the fuel injectors.
2. Inspect fuel injectors for proper operation; clean using a fuel injector cleaner kit if clogged.
3. If cleaning does not resolve the issue, replace the fuel injectors with new ones.
4. Reinstall the fuel rail and ensure all connections are secure.
