alright, what are the codes? then, what have you done to your car? then what was the last mod you did to your car before this problems?

DO NOT , PLEASE DO NOT BUY VETTE REAR OXYGEN SENSORS, its a waste of money and doesn't fix a damn thing

The code will tell you which one it is. Post it if you have it, and any mods too...

Its a 99 trans am that I just bought that is completley stock,I dont remembergetting a numerical codes the scanner stated it was bank 2 sensor 1, the reason im asking is because I know that other users had gotten a SES light after they replaced only 1 senors so im trying to avoid that and replace them in 2's but I dont know if I shoud do the 2 front ones or the 2 rights ones any idea ? Thanks for your replys.

Bank 2, Sensor 1 is the precat (front) sensor on the passenger side. If that was the only code just replace/check the wiring on that sensor.
