Thanks Sam,
I bought a used (but supposedly in new condition) idle stabilizer from  Ebay,
but it
doesn't hum when I touch it with the key in on position as Germain pointed
out (thanks
Germain!).  Do they all "hum" like that?  Maybe I got ripped  off...I'll
check into the Temp
sensor. [I hope that isn't connected to the 02sensor, since my o2sensor has
a "missing"
connector...missing cause we had to use the wire harness from an 1984 we  put
this
thing back together].  Oh well... do you think a bad idle stabilizer  would
keep me from
making it to Minnesota?
Thanks for the advice and zip file ;-)
