Have you changed anything in the last 4 years while the car was sitting?
What I’m getting at is that bump steer doesn’t just appear. It has to come from a change. Like a change in ride height, alignment, or something that has worn out or broken.
And typically, the bump steer on these cars is relatively small. So I would make sure that you inspect everything in the steering and suspension for wear and damage. TT5.9mag provided a pretty good list of the usual suspects.
