Very nice pics, thanks Roger. Good idea about labeling the parts.......I'm gonna do that. Good way to learn what's what and not have to flip open the book each time.

The idle up vavle can br operated by either the p/s pressure switch or by the A/C VSV. Does the same thing, boosts idle speed to keep from bogging down the engine at idle when A/C or steering boost is needed.

So, that plastic screw does control the idle boost speed for the PS? I'm a little slow on the vacuum/electronics stuff.
