Unhappy funky idle

Okay so i bought my first Ford and it was my 2001 focus ZX3 5 speed.Love it !!!!!!Lots of fun to drive then last week i did the "stupid" and ran it almost out of gas since then it has had a rough idle but also noticed about a couple days before that there was like a hissing/sssshhhhh noise.So i did some research and put gas treatment in then that didn't work so i got some trottle cleaner and cleaned the throttle body.That massde it run a little smoother now back to a rough idle at stop lights,like it's gonna die and rpms go down to about 750.
Engine light came on so went to the autozone and some 19001 code came about oxygen sensor.

I love my focus and of course the gas mileage and the zoom zoom of it.
so this weekend my son and i will try the z hose thing.But if any other clues plz let me know.
