Dyno Testing Problem

["Alexander van Gerbig" <Audi_80@email.msn.com>]

    I went to the garage prepared to do the new dyno emissions test.
Everything was fine, the mechanic got the car on the dyno, did all the
computer work, then they needed to center the front end on the dyno.  They
put the car in Drive and let the wheels spin under their own power.  The car
slowly started to slide to the left so the mechanic applied the brakes.  He
let up on the brakes and the car wnadered back to the right side of the
dyno.  The car wandered from side to side twice.  What is the cause of this?
Alignment seems fine.

Thanks!
