at idle it has erratic miss fire, worst in gear (auto),changed plugs,wires, roter, and ignition control mod, adjusted carb idle and mixture...2.8l v-6,'85...vacuum or sticky valve?..whatcha think?

it might be ur O2 sensor(s). mine were bad on my 95 4.3. flooded the engine and caused a few misses. Is ur check engine light on?
