Threw some codes My 05 with 48k miles threw a p0171 and a p0174 left and right bank lean codes. I reset them and have put about 20 miles on since and they have not came back. Could it be a fuel issue? I run 91 octane. Only mods are cai and exhaust that I know of. I made an appointment to have the fuel filter changed tomorrow. Anyone else have this happen?

Its probably CAI related. Make sure there's no leaks in the tubing, and worse case, it may need a tuning. I had this issue when I put on an intake. P0171 and P0174. I went back to stock intake until I can go for a tuning.

I get the same two codes - Randomly at best! I'll go for weeks without issue, then it will happen 3 times in a day.
Thing is, it only happens when the car is really warmed up, and at idle. Never when I'm moving.
My only mod is a Volant, and I figure it has something to do with the CELs.
The car runs and drives perfect.

I wouldn't pay someone to do it Fuel filter is really easy to do & to get to. I wouldn't pay someone to do it.
It's on the passenger side frame rail, you'll need a set of fuel line tools (those little round plastic ones) but those are cheap.
actually, you only need 1 size fuel line tool, but they come in a set.

Thanks again. I have the tools but took it in to get it done and have the fuel system looked at. Seems to be running good. I have a couple hundred mile road trip this weekend so I will see.
