Always good to eliminate the plumbing before calling the electrician. I wonder how that sits with the reported increase in voltage at the idle valve when it occurs?

I'm very skeptical about using "DMM"s to draw conclusions about pulsed waveforms mostly as none make the same integration another might make. But OP reported, I think, an increase in voltage, which, if measured across the terminals would seem conclusive of an increase in duty cycle, but if measured with respect to ground, a decrease. The conclusion drawn was the ECU is mandating the additional air.
