sputtering

anybody know why my 1990 chevy silverado w/ a 305 5 spd. sputter intermatenaly. It will run good going down the road then suddenly when i give it gas or take off it sputters. then it 'll run fine for a littl bit. It starts great and idles great, and revs up great. its only on acceleration. I put new plugs, fuel filter and O2 sensor in, no help.:banghead:

First--Check the fuel injectors for proper spray pattern-cone shaped then check pickup coil in distributer-- new distributer is often easiest way to fix this.
