Curious High Idle Problem

[Chris Dyer]

Facing front of car, look on valve cover. Bolted on the top of the valve
cover is a semi-triangular chunk of metal.  If I remember, there's one wire
bolted to it--that's the ground for the freq. valve.  Let me
rephrase==That's what I was told by the wrench who couldn't fix the problem
for over a year.  For all I know, it's the ground for the seat memory. I
said, "I cleaned this and it's now fixed, what is it?"  Then I said, "Can I
have my money back?" He declined.

Anyway, sand away dirt & corrosion, apply a li'l dielectric grease and yer
off.  Also, remove your ISV and clean it w/carb cleaner, & check its wiring
as well.
