I know that feeling. When I was resurrecting the 560 I was sitting there idling the engine and decided to cycle the sunroof. Everytime I would try to close the roof the RPM would drop, almost to the point of dying, then pick up and idle fine as soon as the switch was released. Replacing the regulator cured that.

I have a bum seat adjustment switch in the back and purposely am not replacing it. It keeps the kids from jacking with the seat.
