2006 V50 T5 AWD misfire at high altitude

So I know I need to replace the PCV but I am getting misfires in Colorado only when I'm topping mountain passes above 8000' or so.

I'm getting mix too lean code and O2 sensor code. Any suggestions?

How many miles? start with the simple - look for vacuum leaks/ intake leaks. its possible the MAP (altimeter) sensor is at issue or the O2 sensor but I'd look for a small vacuum leak first. You may want to have a shop do a smoke test before replacing parts if you don't find something obvious.
