The call it "dieseling" as that's what it sounds like and it is because of excess gas in the combustion chambers. I think this HEMI takes a lot of gas a startup and if the initial throw doesn't turn it over, it adds more gas into the chamber on the second go 'round. Causeing the dieseling sound. Mine does it too. I don't think it is a "Problem" per se, but more of a characteristic.
