There was a theory that something dissolved into the E85 was also more likely to come out of solution when subjected to greater pressure difference on injection like in DI cars. The guys having the issue found that running a tank of regular gas every month or so was one way to avoid the problem as well. Kind of a hassle, but it worked for some of them. That would have stopped me from using it if it was that bad.
