What's the fuel pressure at idle? Should be around 10 PSI. When was it last tuned up (plugs, wires, cap, rotor, fuel filter, air filter)?

http://www.troublecodes.net/GM/ this page will explain how to retrieve codes from your van. Its quite simple and any conductor will work. It doesn't necessarily have to be a paper clip.
