IACV's are annoying, and they're not needed for a smooth idle above a certain engine temperature. In my case, it's around 100F. You'll probably want to leave yours unplugged until autumn rolls around. I've thought about an IACV toggle switch, but the engine kill switch sort of makes that redundant. 0RPM > 1000RPM.
