Jack the car up and try rocking the front wheels back and forth. If they move, then check all the suspension arms, links, and bushings for damage.

A friend of mine had the same problem on one of his old cars - under acceleration the car would pull badly to one side. It turned out that one (out of two) of the lower suspension arms had broken in half, and the wheel literally moved back about 3" when he accelerated, which obvious completely screwed up toe, camber, and all that.

Other than that, also ensure that the car is sitting level, all the shocks are in working order (not siezed or worn out), the brakes are binding, and that the tires are all correctly inflated.
