Hey guys so I have a problem with my car idleing my little cousin decided to mess with the idle screw on my nick Williams throttle body without me knowing and now I can’t figure out how much to back it off or tightened it. Does anyone know of a stock set point car is h/c/I and dies out before I can run to the engine bay and mess with the screw. Thanks guys

if it's idling to low or dying, give it a little more in steps until it idles right. How hard can that be?

Here are a couple of pics of where mine is set...I’ve never touched it. The first 2 pics are with the throttle in the closed position and the last one is with it open to 100%. It looks like when it’s open 100%. The screw is set at the same height as the throttle body and sits flush. Should at least give you a good starting point.



Throttle fully opened.

It is set from the factory to just open the throttle plate enough so it doesnt stick when the throttle is closed. The idle control motor controls idle speed. Do you have a scanner to see how many steps the iac motor is open when idling? Off the top of my head it should be around 30 steps. You may need some idle tuning for your setup to get it to idle correctly.
