2007 runs rough (stumbles) at idle

I am losing my mind.

I decided to buy my first ford product, a 2007 Ford Expedition 4x4. I love the looks, suspension, power and features and I decided to choose the expedition over the nissan armada.

After a few days, I noticed that my engine felt like it was missing or idling rough when in park. This seems to get worse the longer I sit. I also noticed that when reving the engine above 5oo rpms to 200rmps, the engine runs rough. Above 2000 rpms, it seems to clear up.

The vibration or rough idling is very subtle, but it seems to get worse. Also, the rough running can happen during a cold start.

I have visited 3 Ford dealers and they have all told me that this is normal. Anyone else have these problems?

Thanks!!!

-----Update:

I talked to a dealer today who seemed to have an actual answer. When I described the issue to him, he mentioned that it was a common complaint among 07 - 08 owners. He explained that Ford had made massive reductions in emissions by circulating exhaust back thru the engine at idle. he explained that this was the cause of the stumble. He also explained that the brand new ones on the lot will not do this until they reach 25-50 miles on them.

Are there any other owners who can comment on this?

I guess it is subjective. If you have had high end cars that idle as if the cars are turned off, then a Ford will probably seem rough. I do recall the first 10K miles I couldn't tell mine was on unless I looked at the Tachometer, know I can feel something every once in a while. Not a stumble, but more of-the engine is on- type of deal. Nothing worse than any Ford I have owned/driven which includes two 2000 Expeditions, 2005 Expedition, 1995 Explorer.
