I got that code running from Orlando back to NWFL

I got that one repeatedly & also "low rail pressure"

I ordered a new fuel filter :$:
The MP-8 sometimes throws that code when towing heavy. It will clear itself. I don't know why it does it on some trucks and not on others. I have not had it happen to me when towing but a few guys have.
I get the same messages towing, plus the cat full warning. Until this past weekend it has only done it towing, but now it did it driving mountains in Vermont empty. I posted this problem about a month ago now it seems there are more and more seeing this.
