Broke down and got the top of the line Actron. CP9190

Prints to PC, graphs, give hand jobs. Comes with cables to talk to fucking anything. With any kind of luck, I'll be dead before I need a new one.

Turns out, it was the downstream O2 sensor, on the passenger side...

Sub $100 fix, five minutes work

Do little.
 

$31.25, shipped to my door.

...but at least now I can talk to the animals.

Buy an o2 sensor socket. It will save you some grief.

Prolly not a bad idea, thanks.
