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...

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.
