This was it! Thanks for commenting @ridethecliche. Between driving yesterday and today, I put around 20 miles on the motor, dropped the Rotella T1, refilled with more T1 and put 35 additional miles on it. Gonna use the first few hundred miles to fine tune the idle/stalling when coming to a stop, etc.

Hell yeah!
This is what I like about this place. Odds are someone has had the exact same issue as you're having. Brain and Stefanst helped me figure mine out so I recognized it when you mentioned it because that was my exact behavior and both the sensor and the MS were known quantities.
Glad you're back on the road!

Today was a really long one. We tried to find the upper/lower bounds of the iacv and it simply was not responding. We dug into the. Botched wiring from the previous owner and tested continuity for both vvt and iacv. Both weren't working.
Ultimately there was a lot of wire switching and a small output change from fidle to idle with the wire going to the ms3x connector (thanks Aidan) and now we where finally able to get vvt responding and the idle valve can be manipulated in output test mode.
The car is having a very tough time keeping idle without major input from the bypass screw. We may need to adjust the throttle stop. The iacv simply doesn't respond until about 70% duty cycle.
Either way, it's closer than it's ever been to running more smoothly. We just need to reassess why the fuel pump seems to be hardwired on all the time in acc.
There was pizza and beer. But this was a tough day.

These are gamechangers for non-A/C cars.
I can't recommend them if you have to park outside though. The bolts on the lower portion interfere with the corner window seal. I parked outside on a rainy night out of laziness and the inner door panel ended up soaked. I emailed Advanced Automotive last week to let them know about it and I haven't heard back. I'm going to end up cutting my own with HD Racing lexan.
I won the Best Interior trophy at the Miata Expo and within the week, I had my interior torn apart. More on that in the next picture.
I drove to work for autotuning purposes (shoutout 18psi) and entered the parking lot over something similar to this:
The car is at a pretty reasonable ride height, so I wasn't expecting this at all.
So, the carpet had to come up to get this off the car, and one thing becomes another and I have to do some interior updates.
Spray painted the frame rail holes because the previous owner didn't.
Got the frame rail back from the machine shop today. Anything that I feel that will take me more than an hour on, I just bring to them. Extracting bolts, complex cuts like this, etc. Their hourly is $60. I've never paid more than $15 bucks for the random stuff I bring them to do.
I have a few small ideas to update the interior, but the major one will be red carpet. I have an email in to KMiata to get specifics on the color/options of the carpet on their NB2 build. I saw it at MATG and fell in love with it against the red Lotus seats. Also considering powdercoating the rollbar red, but that might be too much red. I'll decide once the carpet is in.
Open to other ideas to do while the interior is out.
