Well, you've tapped out my very limited knowledge of this system. Mine has intermittently thrown an ASR malfunction light, while driving with the cruise on, and only after doing so for several hours of driving. If I pull over and restart, it will reset and all will be well for a while. Has not happened when cruise control is not on.

Hopefully one of the professional techs will weigh in on this...

Or one of the non-professionals. I do believe someone (Arthur Dalton, maybe?) posted some pics of his dissambled throttle actuator within the last 6 months or so -- might be worth a search.
