[T3] Engine stuttering (throttle position sensor?)

[Doug Brashear <dougbrashear@yahoo.com>]

Hello all,

Sorry to have missed everyone at the Invasion :-/ 
Hopefully I'll be able to make next year's.

OK, now for my question.  What started out as a
once-every-5th-drive type of problem is now occurring
just about everytime I drive my '73 Fastback. 
Basically, I'm noticing a spot on the throttle travel
where the can wants to 'hiccup'...the spot is just a
few millimeters from idle, and anytime the throttle
rests in that general vicinity the engine seems to
stutter.  My hunch is that perhaps my throttle
position sensor has worn out in that particular place,
or perhaps there is some schmutz on the contacts in
that particular location.  Is this a likely cause on
an engine that has just over 65K miles on it?  I'm
going to investigate it in the next few days, and will
also check the manifold pressure sensor for oil and
such. Also, not sure if this is related, but once or
twice this summer the car has run-on for a few seconds
after shutting off the ignition.  Any idea what that
might be?

Thanks much in advance for any advice or suggestions!
