Idle hunting issue

So I've been having this idle issue since I finished the swap. I'm trying to figure out what the problem is. I just got done putting in a new idle air control valve and also cleaned the throttle body(turns out they were pretty dirty). But its still hunting at idle. I pulled some codes and they're all pointing at the O2 sensors(P0134,P0135,P0154,P0155). Can the o2 sensors cause bad idling like that? It only does it when its warm btw
