^^^ Yep, I know that code all too well. It's just weird as the is just fine while moving and in boost and all and the idle is sound for the most part but it will stumble occasionally and the AFRs just shoot up real lean.
Did you do the install yourself? I'm curious because there was this little blue thing (I forget what it's called) that was inside the stock line - did you reuse this part or just toss it? I reused it but I think it's keeping me from clamping the hose end down all the way. I mean, the connection is tight and there are no leaks from what I can tell but I don't feel confident about it.
what are you clamping? they provide you with a feed (the braided one that has the fuel line end on it), and the return is your stock one. You shouldnt have to clamp or reuse old parts.
