My 2003 Mazda Protege stutters at red lights. I know my O2 sensor is bad.

Is this why it does that? My check engine light came on 2 days ago. Auto Zone told me my O2 sensor was bad. About that same day, my car started shaking and stuttering at red lights. So for now, I put my car into Neutral and rev my engine so it doesn't happen. Could my car stall out? Can an O2 sensor cause this??
