I have always set my idle using the throttle body set screw on the outside throttle wheel thing as I have seen it adjusted there back when I was pretty much a novice. I will provide 2 pics of the different screws on the professional products tb and also a link to where they talk about adjusting it via that same screw I was using. I'm sure there was someone on a site who said I was setting it with the wrong screw. Last time I set idle and tried to use the other screw in indented hole, the only direction I could go would raise the idle. Going the other direction the screw was tight. NOt sure if I was supposed to keep trying to turn or not so I tried adjusting with the one I always used first then the indented screw. Well that didnt work either. Just trying to verify if indeed the idle can be set or not set with the screw I was using all along.
Here's the link to that thread about the 94/95 tb even though mine is a professional products aftermarket:
