Hi,

I'm not at all sure if the cruise control actuator would be fast enough to
handle the idle speed but it's always worth a try.  The new SAABs are production
vehicles with Throttle by Wire.  What might also work quite well are Model
Airplane Servos.

Cheers,

John

I've considered doing it.  But I decided not to because I can't really see
what advantage you would gain from it, unless you want to have a
semi-intelligent computer controlled throttle for some reason.  The reason
I wanted to do it would be to be able to have logging and assisted
heel-and-toe for track driving.  But you don't need that for logging and I
didn't think it was worth it otherwise.
