Yeah, I wondered if leaky injectors would cause this problem. If when turned off, if the injectors were leaking/dribbling I guess that could do it? Funny that overnight it clears up. Think that the dribbled fuel could dissipate overnight? How much of a job is it to pull the injectors? One of the few things that I have never done on the 22re (always had 22r carbs before this). Seems the fuel injection on these is pretty good but it sur has a lot more controls/sensors/etc to troubleshoot compared to the carbies...
