Check Engine Light Oxygen Sensor

[sloweclipse97]

So I have searched the forums but no one seems to have this same problem. I recently installed a catback exhaust on my car. I had to heat the oxygen senor to remove it and soon after the check engine light came on. I drove the car for a while like this then had the code read and sure enough it was for the oxygen sensor. I bought a universal bosch sensor from an auto parts store. Had the code cleared, and still had the same issue. Now my car bogs when hitting a certain rpm range and seems like it has no power. I then bought a denso sensor to try and it does the same thing. I still have the light and bogging. Could there be something wrong with the wiring or is it the sensors? I'm lost and can't seem to figure this out. Thanks for any help or ideas in advance.

Your front o2 sensor is bad, replace time! It controls fueling so when it goes bad it makes car run in open loop all the time and you'll get terrible fuel milage/performance
