This code shows up for the past 2 years. Car is running great. During this time, I have replaced O2 sensor, clean MAF sensor, smoke test with no leak. No one are able to find what is causing this code to come up.


I used the OBDCOM software to save the sensors when I was driving the car. Please let me know if you cold find any problem. Thanks

Lean fuel condition could be caused by one of the following below:




1.Vacuum leaks

2.EGR and PCV valve.

3.Low fuel pressure.

4.Dirty fuel injectors.

5.Mass Air Flow Sensor.

6.Oxygen Sensor.
