The air-fuel mixture should be maintained at an optimal level and should neither be lean nor too much. So, you should know the signs of a rich fuel mixture such as illuminated check engine light, poor gas mileage, rough engine idling, weak engine performance and excess emissions. See this slideshow to learn the ways to determine too much fuel mixture in the car.

1. Way to Determine Too Much Fuel
Mixture in Car

2. Before ignition, the engine
requires the right amount of
fuel and air mixture.

3. Engine control unit is the main
computer of the car and
controls:
• Emission sensors
• Airflow sensors
• Fuel injectors
• Oxygen intake

4. When too much fuel injected
into the engine, it causes high
fuel mixture.

5. High fuel mixture may cause a
variety of problems for the
engine.

6. Below points define the signs of
too much fuel mixture in the
car.

7. Illuminated
Check Engine
Light

8. Check engine light on the
dashboard can indicate issues
on the engine.

9. Error code P0172 indicates too
much gasoline in the exhaust
gases.

10. Poor Gas
Mileage

11. Too much fuel in the engine
can decrease the miles per
gallon rate.

12. As a result, you will find
yourself going to the gas
station more often.

13. Rough
Engine Idling

14. Rough idling of the engine can
cause high rich fuel mixture.

15. In rough idling, you will notice
your car will be bouncing while
driving.

16. Weak Engine
Performance

17. Fuel and air mixture need to be
balanced before they mix and
ignite.

18. Too much fuel or less air may
reduce engine performance.

19. High
Emissions

20. High rich in fuel mixture will
form carbon emissions from the
engine.

21. As a result, you will get failed in
the emission test of your car.

22. Conclusion

23. High level of fuel mixture may
damage your engine
components.

24. Address the fuel abundance
problem of the engine in the
early stages.
