I had the same issue as with the idle, turned out to be a combination of a bad EGR valve and I replaces the pick up coil in the distrbutor for 22.00, just knocked out the dist. gear pin with a punch and hammer, put the new one on and it purred like a G20 kitten. Before you do that though check your fuel pressure to be between 9-13 if its lower that may be the prob.
I had the same thing happen on our 1991 g20. Found a fuse for the fuel pump was all it was! Hope this helps!
i have a 1990 chevy g20 van and since iv had it i took it for a test drive the first day i have had it and only went about a mile and a half from home and started going up hill is when i had lost power and costed to the side of the road and would start it had sounded like i was out of gas>when i had finally made it home finally after getting it towed i had a mechanic come out and look at it and so far i have replaced the fuel pump and the distributor cap and rotor and the modual all it does it cranks but wont start and i have to keep spraying starter fluid in for it to start and even when i do that it wont stay running itll run for about thirty seconds then shut off could any body help me to figure out what the problem is or what it could be i had gotten the van for my family as it has grown to be pretty big and we have yet not gotten to use it and the only other vehicle we have is a small single size truck PLEASE HELP
