No change after the wiggle test. It only does this once it's warm. Something to do with heatsoak perhaps?

Ill be honest with you lol I have seen a shorted ect do all kinds of funky stuff. My 98 caddy had a bad ect and the dash monitor would jump from 250 degrees down to -40 degrees then back to 200.

Some times my dash would flicker and go on and off ( digital ) . Car would all of a sudden die or stumble so bad I thought it would die.

I swore I had a short some place but after changing the ect it never acted up again. Now mind you I know it was not a ford, but the ect is exactly the same in fuction, and still computer controlled efi engine.
