Not ready: O2 Sensor and Catalyst
I had a CEL go off a few months back because one of the O2s ended up going out but I replaced both of those so they should be good. I've been driving it around a fair amount but probably haven't met the conditions for a perfect drive cycle on any one drive since I live in NYC.
Thoughts and suggestions welcome. If you have any ideas for further troubleshooting definitely let me know.

My thoughts are that I'm suprised you passed several times before with the same set up.
Generally I'd say no, you won't pass with that set up, but, I've been wrong before. Now, different car, different engine, good luck!
