Also will post a vid of it running , as the surging is a slow rpm change , maybe I am missing something completely different .

Surging at idle usually indicates too much air running my IAC - as I understand it - did some digging around... it's possible your new part is malfunctioning. Where you able to give a bit more RPM and see how it ran - by pulling the transmission lockout knob?
