passenger side = bank one, bank one starts with cylinder 1 (I'm assuming at the front)
I'm also assuming that it is
1 2
3 4
5 6
7 8

Right?

I'll check out those vacuum lines.

I have no bout that it needs o2 sensors. Before all of this mess, I was looking at what needed done to restore, and maybe even improve the gas mileage. I was only getting like 13ish mpg. and the o2 sensors were on my list.
Hoping to get this thing running better, and get some catching up done with the maintenance. just gotta take one step at a time. sucks not having a budget to be able to just get it all done at once.
