    Look at the Idle Air Control (IAC) valve first. May not be it, but it is a good place to start.

    Next would be the Throttle Position Sensor (TPS).

    It will jump to about 1500 rpm then drop down to below 1000 and up again then when I drive it will stop it might happen two or three times a week

    It sounds more like the TPS to me than the IAC. Both are easy fixes, though, so it almost does not matter which you start with.
