Before you said it would run at high rpm I was thinking fuel pump relay.

I'm willing to bet that the economy gauge is pegged to one side or the other as well, right?

On the back side of the throttle body, down by the firewall, is a rubber elbow that a vacuum line connects to. You can't see it...but you can feel it. The rubber elbow can be had at Autozone for about $3.

Chances are, this is the problem...your symptoms mirror what mine was doing in 2008. My father in law spent too much money trying to track the problem down, and a $3 part was all that was wrong with it...which seems to be common on these cars.
