I'm one of those with an 04 with the problem. Finally got an error code after four trips to the dealer, but it was an unknown code. They said there appeared to be a vacuum leak around a seal, so they ended up replacing the mass air flow sensor and a couple of seals. The dealer said that he was not at all certain that it was fixed. It has not happen since, but I drive the car very little so that doesn't mean it won't happen again. Deep down I don't think the problem is solved.
