The Nissan Path

UPDATE:
After changing out the O2 Sensor, she started but died out shortly after. I am attempting to work on the last code P0745. Before I do that, any ideas on what I'm doing wrong?

I have a ton of issues with my pathfinder. Changed gasket valve cover due to oil leak and pathy cuts out while driving. Spark plug #2 wire was loose so changed out all spark plug wires. She still cuts out. . Ran scan reader and codes P0325, P0161, and P0745 popped up. Relocated knock sensor (P0325) and now she only cranks and won't turn over. Changed distributor & rotor cap, fuel filter & pump and checked relay along with all fuses and she still won't turn over. Should I attempt to change the O2 B2S2 (P0161)? If so, would you mind sharing pictures/videos? Or if you have any other suggestions and what I should change out. Any help would be very much appreciated. Thank you in advance!

Here's a bump. Did you ever figure this out as I am curious as to the resolution. I would have thought you would have gotten a knowledgeable reply by now. I know we have some mechanics on this board. There is an R50 Facebook group you might try as well.

No resolution. Now my baby just sits in the parking lot. Thank you for the tip on the Facebook page. I'm going try there as well.
