- Replace the fuel filter if it is clogged.
- Inspect fuel injectors for clogs or leaks and clean or replace if necessary.
For Ignition System Issues:
- Check spark plugs and replace if worn out or fouled.
- Inspect ignition coils for proper operation and replace any faulty coils.
For Exhaust System Issues:
- Inspect the catalytic converter for blockages and replace if necessary.
- Check O2 sensors for proper function and replace if needed.

4. Clear Codes and Reconnect

Use the OBD-II scanner to clear the error codes after repairs have been completed.
Reconnect the negative battery terminal and ensure it is tight.
