Not sure, but I'll throw out a few guesses on things to check:

What are you using for a tune on the computer? You probably should start by getting the EGR function removed. Maybe the ECM is going into default mode because of the trouble code?

Are you using a 2 or 3 bar map? Injector size?

Are the O2s in the stock locations? If not, are the heated?

I'm running LT headers and it takes longer for the O2s to get up to temp so the car runs rich for the first 2-3 minutes after going into closed loop.
