Scout II or Bucking Bronco

["CDesPlanques" <adesp@domain.elided>]

IH Everyone,

In the past week or so my scout has been acting up.  When I'm driving in 4th at about 1800 to 2000 rpm at a steady rate my scout II
(304) Acts as if it is running out of gas (you know those first few signs like the bucking).  But if I press on the pedal to
accelerate a little and it goes away, but as soon as I am at a steady rate again it return.  I noticed it in 2nd and 3rd at the same
rpms but not as bad.  I though it might be a gas flow problem but wouldn't it buck worst when I press the gas to accelerate?  It
starts and runs like a champ plugs look perfect, I don't really hear the engine miss or anything when it is doing this.  Anyone got
any Ideas... stuff I should check?  This really isn't a big problem has left me stranded or anything, just a little annoying....like
my t-case shifter rattling....
