Na does it do it when the engines running but your not moving when the cars just ticking over ? Youl notice if you turn the steering wheel lock to lock the revs will dip aswell .... I presume its just were the cars drawing power to something else i would try it with the brakes but my cars kind of in pieces. All the cars ive driven have done the same with the steering though

bounces a bit when idle but nothing major

All my car's have done this.. I didnt see it as a problem as it's Power Steering and ABS. They need power from somewhere.
