Re: [DML] Tuning idle speed circuit

["content22207" <brobertson@xxxx>]

Mine did same thing on its way out (would also stick full open
sometimes -- opposite problem but equally fun). That's when I
discovered manual idle speed circuit. If motor sticks closed, car will
not run without doing something else to let air into engine. If you
don't want to mess with brass idle screws can crack throttle plates
like an old fashioned carburetor (don't forget to lengthen idle
microswitch screw if you've still got Lamda, spark advance solenoid, etc).

My opinion of idle speed motor already known and unfortunately
inflammatory.

(John Hervey's tank baffle indeed improvement over factory design).
