I remember my father turning that screw to try and bring my idle down. Is the procedure the same for a 3.8l V6? If so, I'm all set because I already did it. =) If not, a little help in setting that screw would help. Thanks!

It should be very similar to your engine. I don't know for sure though because your system is OBDI and a lot of things changed. I can found out definitively in a couple days.

That would be great! Thanks.

that screw just slightly opens and closes the throttle body plate. By changing it, you change the position of the throttle shaft, which turns the TPS slightly, which can throw off it's idle voltage reading, which should be around .96-.98V at idle.
