running rough

i have a 1994 chevy astro van new tune up and fuel pump 4.3 liter engine any ideas? thanks.



What engine, Kalley? What did the tune-up include? Did you do the work, hoping to cure the rough condition (and failed?)

Maybe a little more information will help the regulars here to suggest a course of action.
