My truck is doing this bad sputtering stuff. I've changed the spark plugs (bosch platinum), tried fuel injector cleaner. Was told it may need a new fuel filter? I'm at a loss. Trying to diagnose it myself instead of taking it to a dealer. It idles just fine. Seems like at low rpm's around 40mph or so it just starts sputtering. Comes and goes, not a constant thing. Help anyone?

Truck has 80k with the only changes/updates since new is sparkplugs/oil changes/routine maintenance. ALTHOUGH, I have not had the auto tranny flushed. Thoughts?

oh, and my check engine light isn't on.

Did you change plug wires, cap/rotor? The coil could also be breaking down.
