HI Paul and the list,

This technique of adjusting the idle micro switch will ensure that the
circuit opens and closes at the specified .005 after the throttle has
been open, or is closing.  This tell the ECU which fuel map to follow.

It's best to reconfirm your that your basic fuel injection settings are
good.
    1. Then with the engine off, and key off, adjust the microswith.
    2.  Locate the microswitch disconnect plug, my 91it  is just in
front of the throttle body, it has only two wires.
    3. Connect a Volt ohmnmeter lead to each microswitch wire, and set
your VOM to read ohm or just the beeper tone which indicate continutiy.
    4. Place a .005 feeler guage blade between the Throttle body idle
stop and butterfly lever.
    5. observe or listen to the VOM.  Adjust until you hear the tone or
observe continutity with the switch close, and hear no tone or see no
contiunity with the feeler blade in place.


Sincerely,

Mark Keller
