Re: throttle setting out of wack...

It sounds like the ISV is defective/sticking full open.  Try cleaning it and
see if that helps.  Or it could be that the ISV controller itself is going bad. 
Phil posted a loooong time ago that the ISV controller will set the idle
speed over 2000 rpm if:

1) The idle switch is engaged
2) The vehicle is still moving

(in order to keep supplying enough pressure to the brake & steering
hydraulic system).  

Unplug the connector to the ISV and see if the revs drop.  

Also, check the idle screw on the throttle body.  The o-ring that seals
them gets hardened and they intermittently leak, then the screw
eventually gets loose and you get a loud whistle and a big leak.

Best Wishes,

Alex
