A poor alignment will do that. Fieros need a 4 wheel alignment done by somebody who knows what they are doing. If they give you a standard price without checking on exactly what it takes to align an 88 Fiero
, find another shop.
edit: 88 suspensions are different than earlier Fieros.
Possibly because of the mid-engine, Fieros are sensitive to both tires and alignment; when you get them right, the car will drive like it is on rails.
