HELP! Sudden Loss of Power and CELs (Codes are listed)

I'm in a bit of a panic, so hopefully I can get some guidance.

A little background on my car:

E92, 09 w/ 56k miles, w/ Cobb Stage 2, DPs, DCI, FMIC.

Over the past two weeks, my idle has been a little rough and I've had a few hesitations at startup in the morning. I was assuming my valves were dirty (was planning on having a walnut blast done). Was driving just a few minutes ago, headed home (car was warm) and pulled out onto a main street and suddenly my car shuddered and CEL came on.

The car is sluggish, is mis-firing, and occasionally would have an awful smell in the cabin (no smoke on the outside from what I could see). The idle is extremely rough and from 1,000-2,500RPMs the car is a bit shaky and for whatever reason is a bit smoother above that (didn't go much higher than 3,000).

I just plugged in my Cobb and got the following list of codes:


Yup, there's a lot of them.

The only good thing, I had an oil change schedule for tomorrow morning, so I'm hoping they can look at the car. I'll be putting the car back to Stage 0/Stock, anything else I should do since my car is out of warranty?

I would clear all codes and check plugs. Your getting misfires and O2 codes and HP fuel shutoff. Clear them see what comes back and use the misfire troubleshooting sticky.

1) Rebuild to stock 2) Install Cobb/piggyback? and JRZ suspension. 3) Build parrallel HPFP and highflow intake manifold with multi-port fuel and meth. 4) Build full cage and staged twin setup with twinscroll turbochargers. (BW 7670-1.22 / S374-1.25)
