I'd try another mechainc. O2 sensors have nothing to do with the battery light coming on and stalling. Sounds like the alternator is faulty, and drained your battery. Have it checked out.

it turns over but wont start. This is the daughter now.. at first the check engine light came on along with the battery light. then it would die and then start right back up.. now then the oil light comes on and it wont start. I put new o2 cencers, fuel filter and a tune up.. i dont know what to do!!

Maybe the ECU is loseing power or it may be going bad itself. May be a wiring fault somewhere. It's not gonna be a sensor itself due to multiple things failing at once.

Check starter wire to the battery , also might want to check alternator wire I read somewhere the wire rubs on steering column & shorts out.Good Luck

I missed a key fact. You said the lights flickered. That is a sign that the alternator isnt converting voltage right and letting possible unmetered voltage or AC current through. If not caught soon enough can cause havok to electronics. Have the alternator changed. Maybe there is no major damage. If it is still starting back up then it should still be good.
