DP Fix was causing some issues. Went into INPA and saw low voltages in the o2 sensors for the the rear. Removed DP fix, swapped a used o2 sensor into bank 1, post cat. Flashed MHD 2+ back onto the car and passed emissions. DP fix isn't needed to pass emissions in WI, mhd will allow you to pass.
Something noteworthy is that the shielding on the cable grey/ black IS NOT indicative of which o2 sensor. Only way to tell is from the plug color (green or yellow).
