RE: [DML] Idle Problems Solved-Well, Almost!

["Jeff Friday" <DeLorean_Type304@xxxxxxx>]

Hmmmm,

If you're tapping the spool and the idle goes back to normal than it sounds 
as though it needs to "hit" the microswitch to trip it.  Try adjusting the 
screws on the arm that hits the switch.  Make sure the bottom one just 
barely taps FIRST and then the screw above it trips the microswitch 
instantly there after.  You can give the upper screw an extra 1/2 turn to 
trip the switch better but you may need a new switch.  Try an adjustment 
first.

I had to learn the hard way about the brass screws as did a guy I met here 
in NC.  Snug em down with good O-Rings and leave em.  I have developed a 
good method to adjust the screws and manually tune the car by dissabeling 
the idle control system but it works much smoother set up like it was 
intended.  It's a nice method to get the car to a show in a pinch though :)
