You can test if this is the culprit by unplugging it and sealing the open hoses which you just created a vacuum leak and seeing if the idle speed changes to within range. Once you unplug the hose into the inlet of the AAR you should be able to see if the slide inside the unit thru the opening is opened or closed or what. This slide moves shut as the car warms up and thus your idle speed changes. Looks like a crescent moon opening.
Don't assume the WUR is bad.
