I just bought the mechanical o2 fix from gruppe-s and when i installed it the cell light is still on...Is there something im not doing right..I unhooked the battery and jacked up my car put the mechanical fix into the testpipe then the o2 sensor into the other end of the mechanical fix...when i cranked the car my light went off for about ten seconds then came back on and wont go back off.....geez what should i do...im so stressed out about this...

Well it might not be your 02 code it could be something else. Go to autozone and have them pull the code for you it's free.
