O2 sensors

[stock05]

On my 05 GT, are the o2 sensors all 4 the same or different ? When I bought the car it had long tube headers installed and the previous owner had cut and spliced the rear o2 sensors. My tuner says that is causing the check engine light. I plan on buying 2 new ones and was wondering if I have to get rear specific ones?

Have your tuner turn off the rear sensors.

To answer your questions yes the front 02s are differnt from the rears. And i agree just fix the splices or turn the rear o2s off.

FYI, the "Check Engine Light" will have specific diagnostic codes with it, that you can read from your SCT. Do that first, lookup the code (see sticky thread in this section), and then you'll know where the problem is.
