after driving for 2 weeks with the rough acceleration, "2DB4 interface MFL" popped up this afternoon in INPA. Anyone have any experience with this code?

symptoms are the same but different codes seem to be popping up. I tried to do some research and run some tests in DIS and INPA, nothing conclusive. Also not much information online. Again, i cleared the code out and the vehicle is running back to normal.

any help would be appreciated
