The rear O2 sensors are moving around too much. Also, if your cat temp data is in *F, they are def not doing their job... way too cold.
It doesn't take but a portion of this video to see what I'm talking about.
My rear o2 sensor voltage seems to run at a steady rate sometimes, then others one or both of them will start to oscillate around wildly, much like the video you posted for me Noodles.
I have a couple of logs to review in graph format, I just haven't yet. The laptop and the tablet I have to use are getting old, and a real PITA to use. They freeze up and all kinds of mess and it always takes 3 times as long as it should to do anything on them.
