IACV=Idle air control valve. It's what lets your car keep running while it idles and the throttlebody is closed.

Alt is like $75USD plus a core charge and a IACV is $175USD from Honda/Acura no core charge. Both can also be found on Ebay and Ebau.au. To test the Alt properly you need a tester that can put a load on the battery, also called a load tester, VAC40 from Snap-On if you have a lil money. The IACV should stop whining once you give the car a little gas but sometimes it just gets quieter. It has to do with the frequency it is being ran at. The AEM EMS tends to make them whine but the frequency can be changed on the EMS. I would pull the IACV and clean it with a mild detergent and blow/air dry. Might just be a little stuck, not enough to make it idle bad. Also make sure the numbers on it match as it might not be the correct one. Some fit other makes/models/years but run at a different frequency.
