Why does your 2000 Chevy Venture have a surging moto r at idle?

A surge at idle can be caused by a faulty throttle position sensor, idle control valve, mass air flow sensor, manifold absolute pressure sensor, dirty/sticky throttle plate, or a vacuum leak. It can also be caused by fuel pressure or volume that is out of specification, usually too low. It can be difficult to pinpoint the actual cause without a scan tool which also displays real-time voltages of each of the sensors while the surge is occurring. For some of these, you can try unplugging the sensors individually and see which, if any, change engine performance. If not, you may need to contact a professional for assistance.
