[QUOTE="Sluggie24, post: 15629506, member: 184003"] I don't claim to know what is causing your problem, but E85 has a high alcohol content and alcohol vaporizes faster than gasoline with higher temps. Is it possible that you are getting vapor pockets in the fuel rails when it gets really hot out? I wouldn't even know how to check that other than data logging and looking for the forward O2 sensors to suddenly go lean when the hesitation happens. If you know the injectors and pump are good then vapor lock would be the only explanation. If I were to of guessed correctly and that is causing the problem, then the only way to fix it would be to lower the underhood temp. Just spitballing but an aftermarket raised cowl hood, possibly with some air vents in it, might carry out enough heat to fix the issue. Or my guess could be way off who knows. lol [/QUOTE]
