Erratic sputter/misfire through all gears...
On my 5.0 fox when under normal accel I get an erratic sputter through all the gears and when in 5th cruising at 65-75 etc. It seems to go away as I press the gas harder and open it up more. Any ideas? I have checked plugs, changed the distributor(thanks for the dist matt), checked firing order on the wires etc. Could it be in vaccum somewhere? Could my fuel filter be clogged? Any help is greatly appreciated. I just need to know where to look...
Thanks Dave

Coil, cap/rotor, plugs. Sounds like it's in that department.

Is the distributor tightened down all the way? Also, I know that distributor had a stripped screw at the cap adaptor, but I didn't have any problems like that when I was running it.

I am assuming no codes or check engine lights?
Can you do a Key On Engine Off test? I had a similiar condition when one of my O2's went out, but I did get a code and a CEL
