Hi guys, so I had a problem with my iac recently and was trying to get to the bottom of it. The car kept dying on me and all that, and I figured it was my iac, but my dad wanted to put a band aid on it and opened up the throttle with the biss screw..... I know, bad idea, so now i got my new iac and I want to adjust the biss screw back into original position which is hard. Please help me out here, if you know what the distance from the screw to the edge of the hole that its in by using a caliper that would be awesome. thanks.

 

I believe its called evoscan, but you need to activate SAS mode then adjust the Biss accordingly. Loosen it to raise the idle, tighten it to bring the rpm lower

 

that would be great if i had the proper tools, but im on a budget right now, and there is a way to tune it without using the evoscan. i just need someone who has a depth measuring caliper to measure the depth of the stock screw setting and tell me what it is.
