Hi, I have a 2000 Ford Explorer XLS and it currently displaying codes P1309, Misfire Monitor AICE Chip Fault, P0172, System too Rich (Bank 1) and P0175, System too Rich (Bank 2). I tried disconnecting the battery and all these codes came back. Do you think these issues are related? I was thinking it's a Mass Air Flow Sensor. Any thoughts?

Sorry to not get back quickly. The mass air flow sensor has been a root cause of the po172 and po174 issues that I have seen. Cleaning them can work on some occasions.

I have also seen intake gaskets that go bad to casue this as well.
