Car Swerving to Left

Archived from groups: (More info?)

Occasionally, I have a problem with my car swerving to the left while I'm
trying to drive a straight line. The faster I go, the more it wants to
swerve with tires squealing, forcing the car out of control. This does not
happen all the time...many times it drives straight. I use a Logitech 3D
Force Feedback wheel and pedals. I've calibrated them several times and
they seem to be okay. Is there something I've done to the car or might
there be a problem with my computer? I'm at a loss as to how to tweak it to
steer properly.
