    I've got a 97 Astro Vortec V6 and it has problems pretty much the same as yours. I've replaced just about everything in the engine short of the injectors. It runs like a top but bucks every now and then. Good luck with your search for a solution, short of going to a mechanic and having them put it on a scope. I will be doing that myself one of these days when it finally pukes on me.
