    Default What may be causing this...

    With my stock tune (well stock tune with no codes and better fan temps) I am having an issue in Drive. I drive in OD all the time and my AFR gauge reads between 12-15 depending on if I'm going WOT or cruising. But when in Drive only when I hit the gas and let off, the gauge reads 22.4 and I have to hit the gas pedal to bring it back down. Since this only happens in Drive I believe it is not a problem with my gauge (but I could be wrong). What could be causing this? Could there be a problem with the tune, even though it's basically stock? Is anyone else having this problem?
    If anyone wants my tune posted let me know how to post it
    Until I know more about this I'm going to do the easy fix and continue to drive in OD

    That is normal. it is called DFCO. decell fuel cut off. It wont hurt your engine.
