Have any of the maintenance lights come on? It sounds like a sensor problem. It could be a MAP sensor, IAC sensor. What I suggest is for you to visit a nearby Auto Zone. Have them scan the computer to determine if there are any codes stored. I'm not sure where you live, but in PA, this is a free service from Auto Zone.
Please let me know what you find.
