I just got everything put back together, removed the secondary system, and on the test drive, I got intermittent code 55 and code 64. The O2 sensors and fuel pumps are supposedly pretty new, according to the PO, though of course none of that is any guarantee that there's nothing faulty. Where to start looking?

Thanks
Andrew
