What JT said is good
Heck when is it that he puts up stuff that is not good ... NEVER :Word:
The idle on a Stang is controlled by
tb stop screw
tb bleed screw
iac
spark
O2's
and
all kinds of info contained in the pcm
So ... there are many ways to skin that cat
btw ... all the above just applies to a STOCK Stang
If you got mods ...
some OR all of the above ...
can be thrown outta whack
The iac just basically tries to compensate for mechanical load being placed upon the motor such as ac compressor and the like.
Heck Fire ... you even have the pcm boosting the injector's pulse width when
you got a heavy drain on the battery
You can adjust your idle like JT where the iac doesn't come into play at all
or
a good bit
or
somewhere in between.
The thing that can be so is if your mods have hosed the pcm values to
the point that ... NO MECHANICAL ADJUSTMENT ... is gonna help.
Getting back on track here
If the iac is not working properly ... it can cause you some grief
