IACV / Stepper Motor / Vacuum leak

[signalMTB]

My dad's '95 RRC has a high idle at start up, throws the '48" stepper motor code. I've cleaned the stepper motor (IACV) and MAF plug. New IACV is $160 so not super interested in just trying a new one. Might be a vacuum leak...never traced or replaced or diagnosed a vacuum leak before. Any thoughts or help?

You can get one for like an '86 Chevy Astro van that is the same. The part number is 25527077.

does anyone have a good image(s) of all the vacuum lines? Any RAVE reference you could point to? Havent worked with vac lines before so just a little learning curve for me
