FPR performance code

[Philv]

I've read other posts, and can't find anything that helps. I only get this code when it's cold out, like under 70. I thought it would've been gone with efi live, but it's not. LP runs at 11psi at idle and truck runs normal. I'm at a loss.

Can you post the code number up? Not much anyone can do without the actual P number.

Who's tuning? Mods done to the truck? How many miles on the CP3? How many miles on the FPR?
