Holy smokes! The $50 durametric I got off FB marketplace actually works! Shoutout Bethany from VA! It was a pain to get the software running on win11 though I'll say. Jeez.

The camshaft P1 devation is -8.5 and camshaft p2 deviation is -8.8 *with the engine cold and off*. Sounds like that mechanic didn't let the engine warm up to read that. I'm going to put some gas into it and see how that changes. Would be super if someone could pull their cold values so I can compare.

I've got a code for the fuel pump relay (P1124) and the MAF (P0102), but I've unplugged and attempted to run the engine with both of those out at separate points in the last week, so I'll clear those and see if they pop back up.

"Supply voltage" is a steady 11v with the engine off, that doesn't seem right? Drops to 10.x sometimes.
