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.

Yours, David
