07' FLHRS w/EFI, 14,000mi, V&H pipes w/Fuelpak, I always use 93 octane gas with 1/2 ounce of HD gas treatment per tank (thanks ethenol). Now the problem, 2 weeks ago when starting on a warm afternoon it made a lot of popping and felt like it wanted to shut off. I revved throttle several times until it warmed up then problem stopped after a couple more pops when going through the gears the first time. The gas was not old, only about 1 week in the tank. This weekend topped off tank w/2 gallons of fresh gas, started fine, got 5 houses from home and it popped, seemed to be missing , then shut off altogether. Wouldn't restart then nor on Sunday. Checked plugs they're black but no oil or white on 'em. I know plugs aren't the problem, but something fouled them after 4 months. Anyone else run into this? Thinking about checking the codes on my fuelpak tonite? Maybe the codes can get screwed up? Or maybe drain the gas (bad gas still happen?), fuel injector cleaner? Replacing plug wires? Just shooting in the dark before I have to pay local HD $90 an hour to diagnose.
