Update about my car
 

Today, driving approximately 30 mph, the car stalled while driving over a bridge. This also happened rather recently. The drive belt and drive belt tensioner were just replaced about 3k miles ago. The car has also been running kind of poorly lately with a loss in fuel economy and the economy gauge does not go all the way to the left at idle (it is stuck about 1/4 of the way towards the right). I was wondering if any diagnosis can be made based on these symptoms or if anyone has any ideas.
Thanks much
Ben

PS I was thinking of vacuum leaks, a bad battery, and/or bad injectors or seals as the likely culprit. I hope it is not anything like a fuel pump fuel pressure regulator. any ideas on this one?

anyone have any ideas?

The "economy" gauge is nothing more than a borboun type vacuum/pressure gauge; and your symptoms, coupled with the gauge reading, may point to a vacuum problem. I'd sure be under-hood checking all vacuum connections. Perhaps one was inadvertently budged when the belt was changed.
