[s-cars] erratic idle

[Martin Baggenstos]

On my 1995 S6 RS2 MRC software car, on occasion I have been getting this
strange erratic idle after I accelerate hard. For instance, I will give the
car WOT and when I am coming to a stop I will put it in neutral and brake
to stop. During the braking the rpm will come down as normal but will
sometimes dip down to almost 0 and bounce back up. It will then swing
around for a few seconds until it evens out. On a rare occasion, the car
has stalled. Any thoughts?
