Strange Idle Problem in the 6..

[Joe <supertr6@earthlink.net>]

Ok, this one has me stumped.  With the car warmed up I set the idle to 
800 RPM.  It is nice and steady with no fluctuations.  (I have the 
Ignitor installed and an HD8 SU carb) .  I'll take her out on the road, 
drive around a while and when I stop, the idle sits a nice steady 1050!  
Turn the car off or wait about 5 minutes with driving, and she will drop 
to 800 again.  Any clues?  I'm stumped...
