I wonder what screw you're talking about.  The idle adjust screw is a
plug about half an inch across with a big screw slot in it, inserted
in the throttle body where it straddles the closed throttle
plate.  If you've been messing with the throttle plate stop screw
that's a one-time setting done with a feeler gauge at the factory and
theoretically never changed.  Bentley has the procedure to reset it.

In any case your idle stabilizer module should be adjusting timing on
the fly to keep idle rpm to the specified 750 (Federal) or 850
(California) rpm (one module is green and one black, but I forget
which is which).  The base idle has to be set with that bypassed as
specified in Bentley.
