I have a 89 sc 5 speed and its fine when you go from a stop but if your on the highway and you go to speed up not downshift or anything it bucks I have no check engine light Im thinking it may be plug wires I just changed the plugs and it only does it if I stomp on when accelerating if I ease into its just fune and also brand new fuel pump 190lph maybe I should change the fuel filter any help is greatly appreciated Thanks Justin
 
plugs...

99% chance that it is the plug wires. Stock wires can be damaged just by changing the plugs.

Also, I would check your spark plugs. Change one side and see if it goes away, if not do the other side. If it doesn't go away after plug change and checking wires, it could be elsewhere.
 
I have an '89 5 speed.Just about the same
prob.Except I couldn't boost.Plugs & wires
cured it.I recomend using Ford wires &
Dbl.plat plugs. I've heard others don't
work as well.I believe this is for stock applications
