Re: how to set idle up???? Shimming the throttle, adjusting the stop screw
or enlarging the air hole are all going to be
defeated by the IAC unless you go so big that
it's past the IAC's control range. The computer
just will set it back where it wants (550RPM).
If you go past this point then you will have
control of the idle speed, but the engine's
idle will vary with conditions, which is what
the IAC loop is meant to prevent.
Programming is the only way to have both the
idle speed, and the absence of idle speed
variation, that you want.
