If the rear o2 sensors just measure the catalyst of the gases after the cats, will they make the car run odd if I have gutted the pre cats? I am getting a code that is saying bank 2 lean condition. So I was wondering if that is the problem or if one of my pre cat sensors are bad. I also am experiencing a slight studder in fourth gear with the RPM's around 1300 and doing about 35 miles per hour. Are these problems related or is there more things that I should look at? Thanks
Oh and I was also wanting to know if there is any way to shut off the rear sensors, without buying a chip and putting the MIL eliminators in.
