Ive read over it several times... Its not surging.. its bogging.. I hit the gas a couple times in the video to keep it on and also switched on the AC.. it basically idles at 850-950 most of the time.. every time this issue happens the wideband reads lean.. is it possible that air is left in the system after I shut the car off? and when i start it back up it starts lean?

Wideband reads lean, what are your air fuel ratios? Thats not a direct thread on idle but a lot to help out. Im confused air in the system? What air in what system. There may be something to help there, but idle is is just that a bad idle, surge, bogging, stalling, a lot of different issues, and from reading a lot of idle threads lately i havent seen any specific to one idle problem. I never saw one thread when i had a simple idle issue.

I agree.. it doesnt register on the wideband so over 17 when Im having the issues... On the first drive of the day from a cold start it idles at like the 14.5 range.. but eventually after warm it starts to stop registering on the wideband and is lean.. then it starts bouncing from 900 to 0..
