you need an idle air control valve.

Air to fuel metering. Is a carburetor mixing fuel with air not very accurate. Or modern fuel sprayers "Injectors" controlled with a computer like almost all cars. Not knowing what kind of van it is... Ford Areostar uses engine speed. map, (manifold air pressure sensor) and temp sensors throttle position and oxygen sensor's to arrive at the right air fuel mixture. Chevrolet uses Maf (Mass air flow meter) oxygen sensor's engine speed throttle angle and temp to arrive at the correct air fuel mixture. Any good fire starter can tell you when fuel and air are right just a little ignition is all it takes. The best you can hope for is 14 parts of air to 1 part fuel. Know more now?

oxygen sensor maybe?
it tells your car how much fuel to mix with the air that is coming into the engine. if it is not working correctly, then your car will sputter and die sometimes.
this is a pretty common problem in vehicles, they go periodically.
for my firefly it runs about 300$ for the upstream oxygen sensor and 200$ for the downstream.
but for my mustang is was just 80$ for the sensor.
it shouldnt take more than 20 minutes to take out and put a new one in.

air fuel meter is oxygen sensor or also known as O2 sensor.
