I have a '92 chevy silverado k1500 with a 350..sometimes when i stop at a stop sign or something the truck will idle down to 100 or 0 and bounce around and almost die..i hooked it up 2 a diagnostics and it read the oxygen sencor so i replaced it but it really didnt help..any ideas?

I had the same problem in my 93 Chevy. I'm not much of a tech guy so my dad messed around the with altenator and the battery and my problem is fixed. The only problem now is that when the A/C or the heater is on my engine revs up real high and then drops back down. It's likes it wants to just take off. I'm not sure what that problem is. Maybe that will give you a little assistance. But I doubt it.
