Ah...I'm outta town (Kingston) from tonight until Sunday evening. One of these days.
My car goes in to the shop Tuesday to have the console replaced, and the throttle rise looked at again.
(boot around emerg brake handle loose since tranny work last year. No big deal until I noticed a bunch of things I thought I'd lost - pens, backup TH plug, lighters, etc. - had actually slid from the little console tray into the brake handle mechanism. can't fix just the boot; need whole new console)
