No need for a matched pair. Save that idea, though, for the alternator belts.

Yes, both LEDs glowed on my breakout box gadget, but really they were flickering alternately at a good rate. I haven't tried it, but I expect a dwell meter connected at either 10 or 23 would show you the net opening of the IAC valve. That might be a better troubleshooting approach than LEDs once you know (as in your case) the motor is actually doing its thing, which you should be able to tell by feeling the vibration.
