Mazda 626 10700 miles.
I got a check engine light recently. It was diagonised for a oxygen sensor failure. Replaced the sensor but got it back within 30 miles. Another sensor had failed so replaced it again. After 10 miles, the checklight is back again.

Is there something wrong with my car or I need to consult some other automobile engineer?

Usually a faulty catalytic converter will throw the oxygen sensor code. I suggest having the cat. converter tested. If it is bad, it can also cause the sensors to go bad..
