1988 -2.9 surging

The engine is surging bad while accelerateing in all gears at all rpms?? Any suggestions. I was told the term is trailer hitching?? Any help or suggestions would be great before I start replacing everything. Just did a tune up cap, rotor, plugs but no wires, fuel filter and is getting worse.
