I would try running some injector cleaner through the system or even removing that injector and cleaning it. Unless I am misunderstanding the problem, but it just sounds like a dirty or cogged injector to me.

dont try to raise fuel pressure necessarily, it just means that your oxygen sensor took that reading. I've had it and cleared the code and it never came back.
