I'd replace the o2 sensor(s).

Not sure on the exact specifics of narrow bands, but a wide band o2 gives off voltage in the presence of oxygen and none (or near) without. I'd expect a misfire to cause an o2 voltage drop.

When was your last tune up?

Tbagg1ns - great appreciate this. Yeah so FOR NOW the oil pressure code is gone. Maybe it was being thrown as the car died and the switch saw low pressure enough vs rpm.

Had the same thought. Most misfires are ignition related. Plugs and shit should be your first thought imo. You could do a resistance test if you wanted.
