31- afm could be going tits up. Get it tested.
34-either a boost leak, or you're hitting fuel cut.
anyone have any other opinions?

I was tossing code 34 from hitting fuel cut cause i was an idiot and just reset my ecu and it cleared fine, see if that helps just make sure it atually goes away.

Did you happen to clean your AFM (with electronics attached) recently with something like carb cleaner?
Code 34 is fuel cut...you will hit it boosting between 10-12 psi on a stock AFM. Otherwise, it's likely a boost leak.

That's good...don't do it. Cleaning an AFM w/ carb cleaner is one of the best ways I know to kill it. Test the AFM per the link above.
Even if it passes the above test it could still be bad. Which is what happened to me veryrecently. It passed the diagnostic test, but still didn't function properly. I bought a new one and it works fine now.jdub said:
