Default Weird o2 readings

I think I already have the answer to my own question but would love the input..I hooked up car to atap today and o2's reading funny...drivers side would idle and cruise at .020mv at idle and cruise but but would spike while cruising, but would stay around .015-.030mv most of the time and would be pretty steady around.890mv at WOT.the pass side stayed around .450mv the whole time give or take .010-.020mv..Would the fubared pass side O2 affect my drivers side making it all crazy...? The driver side dont seem to switch fast enough..You think both are jacked?
Hope this all made sense..My ltft where 0 with a couple spikes random -88.3% spike on bank2 ...Id enjoy some input..
Thanks
Jon

Sounds like your car is in open loop and no longer referencing the O2's. The PS one sounds like it is unplugged.

Are you tossing O2 sensor codes?
