What is your commanded IAC steps when idling? If it's down at zero, you have a vacuum leak. Check your throttle body shaft for slop. The TB to manifold gasket is a common area for leaks.

...and verify coolant temp sensor. If the temp sensor is showing a false low temp, the computer may be deliberately running "fast idle".

I verified this morning the coolant sensor was the same as ambient Air temperature

I think it was the IAC even after swapping it out with two other ones I think the wiring might be playing an issue it just started up when I went to take another dats log and idled fine took it for a drive for over an hour and it still seems to be good it was around 65 counts and 40ish when warmed up when the IAC is functioning properly I'll keep it updated after work tomorrow
