1990 Chevy Van with a 350 small block that has a mind of it's own.

Try to get it running a bit to warm up the exhaust. Take a point and shoot thermometer and take the temp of the cat. If temps exceed 400 degrees I would start to suspect a plugged cat.

1990 chevy lumina, idling problem...stalling...too rich

Stalling and running rich. I have seen this before on a Camero. The fuel pump was weak. Not making enough pressure. This caused the fuel injector to DRIP gas instead of SPRAY gas. This caused the fuel to flow into the cylinder in a liquid form, and it did not burn well. We put in a new fuel pump and the car came to life. Good luck.

1994 chevy lumina van. It will start and idle but stalls when gas

Try replacing the throttle position sensor. I had the same problem in my truck. It would start and run for a bit but as soon as you let off of the pedal, it would die. Try it and see if it works.
