service engine soon!

I have a problem that i still cant figure out and maybe someone can help.
about a month ago the service engine soon light came on so i just like anybody took it to the shop. they did the service on it and i got the car back and the light was off. so about a week ago the light came back on so I started to trouble shoot it on my own and found that it was spiting out a code for the O2 sensor so i replaced it of course and the light stayed off for about a day and then it came back on and i then noticed that the light stays on for about a good 15mins then goes off for the rest of the time its running.
the light comes on every time i start the vehicle
if any body can help please get back to me

you didnt metion what year car. could be it is (ECU) is still getting and error for the O2 sensor, you didnt say if the car was cold or hot. When the car is cold the ecu really doesnt use the o2 until it is up to temp then it switches from closed loop to open loop (uses all the sensors)
