Looking for ideas. According to my scan tool, it is showing my B1S1 O2 stuck at .423mv, B2S1 at .389mv and both LTFT and STFT at 0. Any suggestions what may be causing this? Maybe a bad ground? Popped fuse? I would think it would be really strange for both O2's to die at the same time. Also, correct me if I am wrong but if I understand the STFT correctly, shouldn't they be throwing fuel to it based off of the low O2's? I haven't really looked at anything on the car at this point but plan to do so tomorrow.
