general problems of the 2011 Nissan Maxima

Takata recall. At 80k miles my vehicle is idling while in park and also while accelerating its doing a jerk and feels as if it doesn't want to go into gear to reach higher speed. I checked the code and it read as a air mass flow sensor, catalyst converter, and O2 sensor. The car turned off on me while on, jump started it and turned back on. I changed the mass air flow sensor and its still doing the same thing. I took it to the mechanic and the mechanic said the code says battery and other things. Reccommended we start cheap by changing the battery and going from there. I changed the battery and the computer now says O2 sensor. I keep dumping alot of money into this vehicle and to me it seems that this issue is also happening many others including my close friend who owns the same vehicle.
