Hi Rich.

Your car is exhibiting "bump steer". You can look it up on the 
internet. It's caused by a change in direction that the wheels point 
as the wheel moves up or down through it's suspension travel, or an 
assymetry in the frame or suspension, or other things. It could be 
as simple as a bad alignment (just because the car doesn't pull to 
one side or the other doesn't mean it's right) or as subtle as a 
bent frame which is putting more weight on some wheels than others. 
Since it's not a common complaint to Delorean owners in general, it's 
a good guess there's something wrong with your alignment. 

It can be very difficult to diagnose and eradicate. I had to do it 
on my car, and it took about 10 iterations.

One thing to look for right off is rear toe out. If your alignment 
guy accidentally pointed the wheels outwards too much, it doesn't 
take much, the stability of the suspension is decreased. You might 
consider asking your alignment person what alignment specifications 
were used on your car.

Good luck.
