1 easy thing to do is fill a spray bottle with soap and water and mist your manifolds where the gaskets are and all if your air lines if u see bubbles or you hear ur engine make sucking sounds or just bog a little then u have found ur problem, hopefully what I have said helps you out cheers
You should remove your intake manifold and throttle body and replace the gaskets that was my idle problem on my audi a4 as soon as I did that all idle hunting disappeared, mainly I would say its a vacuume leak easiest way to tell is if you have a boost gauge ur car should pull somewhere in the neighborhood of 20 on the vacuumed side at idle so check all of your vacuumed lines including the bigger rubber ones and the ones under ur intake manifold and check ur intercooler for leaks
