Disconnect the battery to ensure safety while working on electrical components.

2. Addressing Error Codes

Using the OBD-II scanner, note down the error codes retrieved.
Refer to a repair manual or database to interpret the error codes for specific issues.

3. Repairing Identified Issues

For Ignition System Issues:
- Remove the engine cover (if necessary).
- Replace faulty spark plugs and ignition coils:
  1. Disconnect the electrical connectors from the ignition coils.
  2. Remove the ignition coils using a socket set.
  3. Replace spark plugs with new ones, ensuring proper gap settings.
  4. Reinstall ignition coils and reconnect electrical connectors.
For Fuel Delivery Issues:
- If low fuel pressure is indicated:
  1. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
  2. Disconnect the fuel lines at the fuel rail and replace the fuel filter if clogged.
  3. Reconnect lines and install a new fuel pump if necessary, following manufacturer's specifications.
For Emission Control Issues:
- Inspect and replace any faulty sensors (e.g., O2 sensors, MAF sensor):
  1. Disconnect the electrical connectors from the sensors.
  2. Remove and replace the sensors, ensuring to apply anti-seize compound on threads where applicable.
  3. Reconnect the sensors.

4. Final Steps

Reconnect the battery.
