Throttle sticking - I think

[Christian Williams <delorean@xxxx>]

Well I've been trying to pin this one down for a little while. The
situation is that when i drive around for a little while, my throttle
appears to stick and I idle at around 1500 RPM. The throttle spool appears
to return fully, but it's not until I push down on the arm (the one that
trips the idle microswitch) that it drops down to about 900 RPM (where
it's set to idle). I adjusted the screw that trips the microswitch, but
that doesn't seem to be the problem. When idling high, I've taken a dowel
and triped the microswitch without disturbing the arm. No difference. But
then when I press the arm down, the idle drops to 900.

Is there something else that that arm is tripping? Something else that
needs to be adjusted?

Happy Halloween!
