IAC rest and reset

[Snowwebs]

I keep seeing a blip on my IAC.
It goes to an "IAC rest in progress" and an" IRC reset request", the motor position shows a jump from like 80 to around 256 and at the same time the desired motor position goes from 80 to 0, then the motor position starts counting down and gets to around 5, then the desired position goes back to like 68 and then actual position counts back up to 68.
All stays normal for a while, but then anywhere between 5 seconds to 20 min the reset starts over again. Each time the whole process takes only a second or two, and almost always when my speed is at 30 mph, a few times it was somewhere between 29 and 32 mph, but never anywhere else. neither the map, throttle position or any other data seems to have a relation that I can find.
I've seen it do it many times before and never really paid much attention, untill recently it started setting the IAC fault code that seemed to be repaired when I replaced the IAC motor.
But, it still does the whole reset thing.

I'm wondering if anyone else has this, and what causes this to happen. I cant find any settings or info about it.

This is a 7427 computer runninging a 95 k2500 with a 496 stroker/4l80e, it was a $OE originally but now running a $31.

Thanks for any help or thoughts
