Sputtering during acceleration

I have a 2001 Expy. with 86k on it. I noticed a rough idle intermittantly and sputtering during acceleration. I replaced the plugs, checked and replaced some vacuum line, replaced the fuel filter. I'm not sure what to do next. There are no codes being set. Does anyone have any Ideas???

sputtering

no codes I presume? Why not try a bottle of fuel injector cleaner at next fill up?

I have since cleaned the M.A.S. , throttle plate, I.A.C., and run Lucas fuel system cleaner through the system and still the same results with no code. Sputtering/misfire under acceleration.
