Post subject:  O2 sensor "slow response"

I just replaced my O2 sensor (bank 1, sensor 2) and erased the error code it was sending. After driving it around awhile, the check engine light came on again. I went and checked the error, it says "CKT read slow response". Does anyone know what is causing it to read this error? I replaced the stock sensor with a Bosch sensor from Advance Auto. I figured that since it was a direct fit sensor and not just some universal sensor, that it ould work fine. Any ideas?

It has come on a couple times in the last week and half since replacing the sensor. I have erased it twice now, was weird cause i would put 50 or so miles on the vehicle. Turning the vehicle off and on as I would go run errands and all. Then it would just pop on again. Its off now, but I just cleared the code the 2nd time yesterday. I am just counting the miles til it turns on again.
