For those not reading the War and Peace thread on it, we had a behind the scenes team of the guys Doc mentioned doing various tests, etc with, AFAIR, Doc and Max doing the posting to keep the clutter down.
Hey Doc, I still have all those emails from you and Max on all that. And I haven’t used the diagnostic tool since then.
My almost 75 year old brain forgot about your oscilloscope! That was a great team effort!

And the shortcut involved getting the airbox out from memory, just be aware of the sensors on the airbox.

Powerdubs might have some methods as well, he specializes in airboxes.

Might give you some poiners
Max, I may be to blame for this, as in post number 782 of the epic thread, I commented that I would be tempted to give it a shot of silicone spray lubricant before reassembling.
In the late 90s, the automation company that I retired from designed and built an automated assembly and test system for General Motors EGR position sensor. During the assembly, contacts (multiple-redundant) received a shot of silicone spray, which was good for life.
Same lubrication process used for the concept of a drive-by-wire automotive throttle switch.
It may not matter as much with the IACV, as lubrication would not be applied to a closed system, however, it might prove useful for component run-in and the air supply is filtered.
I used to suspect that there was some binding interfering with the stepper motor travel, but I've latched on strongly to your heat affecting the magnets theory.
