Contacted Spike about this and sounds like it could actually be the temp sensor. I pulled it out and checked the resistance and compared it with my spare. The one that was in the engine gave me 1.93 OHM's and my spare was 1.65 OHM's. Higher resistance means it is probably faulty. I swapped them out and will run another tank of fuel through it and see.

Ok, here you go.
First start this morning O2 readings were "--"v's.
After about 30 secs they became responsive and the numbers went from the .9somethings (always a 3 digit number on my scanner)down to the .0somethings and back and forth they went all the way to work.
They changed numbers as fast as my scanner could keep up.
Same thing coming home.
Rear O2's, left rear read 1.020v's, never changed and the right rear moved like the fronts but not as fast and not as big of swings either.
Rear O2's do nothing, no check engine light, so I'm not worried.
My front O2's have about 2,000 miles on them, I only use premium fuel and my truck is well tuned.
Hope this helps.
