    Hey all ! My 4.0 runs generally good , some times great , occasionally kinda rough.Always starts perfect .Have checked vacuum lines , plugs , coil packs , everything looks great.
    The only time I got a favorable change was when I cleaned the MAF sensor, it did not appear to be dirty at all but sprayed it as one would if it were .It ran much better for a day or two now back to same program.
    I unplugged the MAF , still runs same poor .
