Apparently the o2 sensors have not been your problem, what does the scan show in the way of codes. Have you had it scanned lately. Give us the codes and maybe we can help direct you to the actual problem. If it shows o2 sensor, do not replace another one until the issue for it to mention the sensor has been repaired.
sounds like you need a 2nd opinion and its to late for warranty on previous work
