Suggest taking it to someone who knows what they are doing. It has nothing to do with the fuel you have in it.

Agree with the above diagnosis but have another related question. Our Club Car has backfired a few times but it is an EFI, so the above is not relevant. Any ideas what could be causing an EFI to backfire?
