Subscribed, I believe I am a victim of the same problem.

This issue has been going on for about 6k miles. The dealer could never find what the problem was since it never would throw a code. Last week I finally had enough and broke out my own tools and started retracing there steps and removed the intake plenum myself. Mysteriously the car ran perfect after that. I found nothing out of the ordinary that would have caused the problem. I suspect that there may have been some debris within one or both of the idle actuator hoses that I cleared innadvertindly. If it comes back I know what to look for now. Ashame I am having to do my own investigative work and repairing to my own $65k car...
