Sorta related.. I use smoktek dual coils in the 2 and 2.5 ohm types. I find during use they dip as low as 1.3 ohms, at which point I get an e2 (i think, some low number anyway) and have to turn voltage down to make it go away and get the last bit outta the carto. It consistently reads low even after sitting overnight so it isn't heat related so much as age/buildup. Since yours are still measuring at 3 I agree it isn't likely the same issue.
But, if the cartos are from a wonky batch, its anyones guess.
