P0088...fuel rail pressure too high. How often do you guys get this code? I got it for the first time a year ago when I was on the dyno for the first time. Cleared it after the dyno run and never saw it again. A month ago I got the code down at the dyno, and again cleared the code, no big deal, truck ran just fine.

Now I get the code whenever I am pushing the truck hard. It will clear itself after a few days and the truck runs fine. Is there anything I should be checking? I searched on the code, and found a lot of people having trouble with their fca and their trucks not or barely running. Mine runs just fine, I just get the code everynow and again.

Just want to make sure there is not something I should be checking or changing. Both times at the dyno I had rail pressure set to 4, so I know that is why the code was set then. But for daily driving my rail setting on the smarty is 1 or 2.

I know my injectors and my airdog are both in good working order.

Thanks,
Alex
