I have a 1990 F-150 w/the 4.9L straight six. What could cause this truck to surge while accelerating?

Many things. Need more details. Auto or standard? Auto may be your fuel system, timing, transmission, vacuum.. Does it do it in all speeds/gears? consistantly surging through out the range of RPMs? Engine Light on? You the original owner? did it come from another state? is it carburated/efi? Need more info
