throttle set screw
I have a 91 F150, 300 I6, e40d, 125,000 miles. What does the throttle set screw actually do? I've looked in 3 repair manuals and it lists the part but doesn't tell what it actually does. I see a sticker on my throttle body that says not to turn it counter clockwise. I think I kinda know what it does but I'm not sure. I probably should mess with it though.
