Missing SAS Screw?!

[eat-sleep-stealth]

Alright Everyone, So I am in the middle of changing my lifters to the 3rd gen ones, and was looking over my throttle body when I saw something that didn't look right...I have absolutely nothing in the hole where the fixed SAS screw should be!

Now, I know that the screw is a sensitive part of the idle and throttle position on the car, So how bad is this? I am obviously going to find a screw and lock-nut to put on there, but is my TPS going to be all angry now? Would this explain why my idle is waaaay to high on cold start? Although, surprisingly, I really have no other issues with idle or the car running besides some random misfire I am still trying to track down...

Oh, and for kicks and giggles check out some critters home that I had to excavate out of the abyss below the fuel rails lol

There is instructions for setting the SAS screw. Once you set it, go ahead and check the TPS setting too to verify it is correct.

Thanks Stealthee, I have actually seen you post the instructions in past threads I have searched through, so that is what I will be using! Still befuddles me as to how this happens lol

I've seen it before. Had a guy stop at my house to buy some parts before and we got to talking cars and he mentioned how his idle was all wacky. I went to check his IAC for him and noticed the SAS was gone. :dontknow:

Problem is the fixed sas is the main throttle stop so the butterfly has basically being jamming/ binding in the throttle housing.
Have a good look and make sure it isn't damaged at all.

Wind your new screw in until it just touches the stop tab, then wind it in a further 1 and a quarter turns and lock it off.

I bought a second hand tb to refurb and you could tell instantly the sas was wrong as it stuck slightly before opening by hand (due to the butterfly binding on the housing).
