Just checked and they're both moving with a 9v.Can you bench test the ICV with a 12v battery and test wires? This may help to settle if you have one, or two good-bad ICVs.
Good point. I had a cloth between the paper clips back-probing the MAF connector today.With a high-impedance DVM the risk is low, BUT it's best not to tempt fate. I mean, if you slip and touch the probes together you've just shorted the ECU, and that's not good.
This idle issue is mentioned quite a few times on the BB, but generally there's no follow up.
