92 5.0L 5spd throttle body injection. Car stutters when it starts moving and then will suddenly start moving like nothing happened. never dies though. It goes away after a few stop and goes than runs fine. Ignition is all new so it's not that.

 

I dont know if its the same for the manual cars as it is for the autos but take a look at the idle air control valve. If it sticks partially closed or is sluggish, it will cause the engine to bog down on throttle tip in because the fuel mixture will be momentarily very rich. I had a similer problem as well when the bearings in the rear of the IAC froze solid and it got stuck in one position. Try cleaning the IAC and see if it helps. The procedure has been covered here before so do a search.
