17 mpg is... Not that bad. And I bet you just made it a bit higher.

Fan clutches can make all sorts of funny noises when they're fubar. With the engine off and cold, reach in there and give it a spin. What does it do?

Install a new fan clutch and glass packs OP.

Just buy a SPAL electric puller fan with thermo switch kit from Amazon and replace the mechanical fan with it. They’re pretty inexpensive, high quality, and easy to install, then you won’t have anything to worry about.

I like this option best in this application. It leaves the AC fans as a separate and redundant cooling option for this unobtanium motor. They cut on at 95c regardless of AC operation correct?

If it was something common I would think it was unnecessary - here it's good insurance.

A fuel restriction bad enough to affect idle would almost certainly prevent the engine from reaching higher RPMs, and it's actually running pretty well if you keep the throttle open, yeah?

In the video it seems like it's running so rich with the throttle closed that it's flooding the plugs. How does this engine management system handle idle control? Is there an IACV that could be clogged or stuck?

Does it ever act up idling in park, or is this exclusively something that happens at low load in motion?

Well it's almost certainly an engine management issue, but your system is unfamiliar to most.

Have you replaced O2 sensors, or priced them? As "throwing parts at the problem" goes, it may be worthwhile since so many other parts seem to be bespoke and expensive.

Definitely hunt vacuum leaks - but the sort of issues you're having would take a pretty major leak that would (I think) definitely affect idle pretty dramatically.

If the ECU isn't getting an accurate coolant temp reading, it's going to cause all sorts of fuckery with idle speed and fueling.

Oh well yeah that's possibly true lol. I can tune a carb and I can work with OBD2... The poo poo in between is like Pandora's box IMO.
