Well, I re-pinned the CKP sensor's plug, the wires had been ripped out because somebody thought it was a great idea to zip-tie them to the stabilizer bar, which moves as you steer. Sigh. So the CKP sensor code is gone now, seems OK.
I also replaced the thermostat, so the engine seems to be running warmer now. Cleared the codes, been driving it around town for a couple of days, no more codes yet. But just tonight I got a "provisional" P0125 in the codes, so it seems like it's thinking about throwing that code again.
I did a full live-data scan of it sitting idling in the OReilly parking lot, and a couple of pictures of the scanner output are attached. Anything in there look out of range?
