B18 not getting enough fuel??

Hello everyone!
I have a 98 civic hatch with a B18 non vtech out if a 93 integra. Recently the check engine light came on and problem code 01 comes up (OBD1). That code is for oxygen content. So I figured O2 sensor. (Was I wrong?) So I replaced the O2 sensor with a new one. I cleared the codes and the code continues to appear. I have noticed that the code appears when I climb a mountain or if I'm pushing it a little hard. I also notice that my air/fuel ratio gauge goes from staying with 12-14 to being pegged at 20(which is the limit). I believe that the engine is not getting enough fuel for the amount of air going into it. Am I wrong? What sensors do I need to check or replace to see if something is wrong? Thanks for your help. I'll try to answer replies quickly and to the best of my knowledge.

It was swapped for over a year now and it has started happening within the last month.
