So the other day I was driving home and my car died on me. It started misfiring and as soon as I clutched in the car dropped to zero. It wouldn't bump start or turn over. Cranks for days at ~300 rpm but won't turn over. Checked my codes and got an o2 code from my punched cat, a misfire code on both rotors, and a lean code on bank 1 sensor. Maf is clean, plugs are fresh, oil is low but not empty, Filters are clean, coolant good, no smoke, no clanking.
I had it towed to the dealer for them to check it out under warranty but what can I expect them to tell me? Fuel pump, coils, compression? They don't want to run a compression test as part of their diagnostics until the very end, but I plan on insisting on one. My issue is the lean code, the only vaccum hose I have issues with is my vfad and that is from the previous owner breaking the solenoid. I have that line plugged at the throttle body so it shouldn't be that causing my issue.
Does a lean code with the 2 misfire codes mean I blew something up in my engine or is it just my ignition/ fuel system not being up to par? Or is it more likely just an air leak issue, although I can't find any discernable leak location.

What can I expect a Mazda dealer to tell me about my cars issues?
