What *SHOULD* the coolant temps be for "normal" driving? I know the temp gauge is borderline useless, but I'm driving with a live OBD2 readout on the phone so I'm normally seeing it fairly steady at about 201 F.

I also replaced both front O2 sensors yesterday during my lunch break, haven't had a chance to get under the car to deal with the 2 rear. Front sensors are cycling heavily when I log them, rears are relatively steady at 0.4-0.5.

Now that I have the "luxury" of the 30 day tags, I'll probably drive it for a day or two, see how it does, and then replace the rear o2 sensors and clear any codes and re-start the process if needed.
