Clean the maf and check the IACV. Start ruling out the electronics. I don't think that you have a boost leak but go over the vacuum lines. And also make sure that your intake manifold isn't leaking by spraying carb cleaner or brake cleaner around the gaskets while it's idling. I noticed that you don't have the bov recirculated and that will cause similar symptoms but mine was never that bad so it's probably a combination of a couple small things.
