02 Chev Express Mis-Firing Maybe?

The 4.3 is usually a good engine, the place I work for had an Astro van with

192,000 miles on it, sold it to someone that works there and now has 310,000 miles on it.

I would get it on an OBC scanner and see what shows up.

Every once in a while one does get past them though, a few years back I tore down a 4.3 that got turned in to a junk yard for exchange. I disassembled the engine and found a broken drill bit where they cross-drilled the crankshaft. Maybe if the drill bit wasn't in there the person would not have needed the motor out of the junk yard?

on the missfiring i think thats what its doing, it happened to me on my firebird. one of the posts wasnt firing and thats what caused my problem.
