3. P0172 - System Too Rich (Bank 1)

4. P0300 - Random/Multiple Cylinder Misfire Detected

5. P0301 - Cylinder 1 Misfire Detected

6. P0302 - Cylinder 2 Misfire Detected

7. P0303 - Cylinder 3 Misfire Detected

8. P0304 - Cylinder 4 Misfire Detected

9. P0420 - Catalyst System Efficiency Below Threshold (Bank 1)

10. P0430 - Catalyst System Efficiency Below Threshold (Bank 2)

11. P0442 - Evaporative Emission System Leak Detected (Small Leak)

12. P0455 - Evaporative Emission System Leak Detected (Gross Leak)

13. P0507 - Idle Control System RPM Higher Than Expected

14. P1081 - Fuel Control Mixture Too Lean (Bank 1 Sensor 1)
