[DML] Re: Idle Adjustment - idle varies from 600 to 1200 rpm and almost stalls

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

The *best* way is to do it with the throttle plate assembly off the
car but you should be able to do it with the "W" pipe removed. You
want the plates closed all the way but you don't want them slamming
against the sides of the body. The stop screw is supposed to prevent
the plates from hitting the sides. Once you get that screw set put a
drop of your wife's old nail polish on that screw so you never touch
it again! Once you have that screw set, then you can adjust the screw
that hits the idle micro.
