it sounds like you've already checked your air box. doesn't sound like you have an aftermarket/modded intake at all. that should rule out vacuum leak. should.
the temperature has been wild around here, but you indicate it does it at intervals not in line with specific temps.
you said you've got an e85 kit--correct me if i'm wrong, but doesn't the e85 kit require a tune to correctly interface to read the ethanol content of the fuel and adjust fuel trims accordingly?
the stock tune wouldn't include that component.
could it be your e85 content sensor is mucking up the fuel trims?

That's a good point maybe my flex kit is faulty. All the tunes I've been running are flex tunes so it would make sense. When I went to the stock tune I ran a tank of 93 before flashing it, and I reconnected the upstream sensor and disconnected the flex kit. I'm not sure how to test the flex sensor for accuracy.
