Anyone going?
I met a few other Comanche owners there last year.
I'll be there all weekend with my truck helping my friend Azzy, from Azzy'sDesignWorks.com run his booth.
It's the Snap-on MT2500.
You also need the 1999 Jeep cartridge and cable.
It basically gives you real time sensor data for everything.
Worth every penny in my opinion.
The older scanner is only $200 or so. I bought one. I've never heard of anyone checking the diag port with a multimeter though. Usually you test each thing directly.
I figured it out!
Here's the video from right before replacing the O2 sensor:

And now the video right after replacing the O2 sensor: https://vimeo.com/123570183
Now the O2 volts go up and down, along with the fuel mix going rapidly Rich/Lean like it should.
Thanks for all your help guys!
Here's two more videos, hopefully easier to read too.
The first one starts from key on, then running at idle.

The second video is it running at idle fully warmed up.

I bought his last black interior off of him for $500. It was literally everything, dash, bucket seats, carpet, headliner, three spoke steering column, etc..
Sorry you guys are having trouble seeing it.
It plays much more clearly on my phone, which is also why it was sideways.. I'll try again when the weather gets better.
