    yes its back firing through the exhaust, but intermittent it also has power loss and is hard on gas.... i looked under the hood and it calls for dual prong sparkplugs i used the single prong ones.... it doesnt run bad all the time thou just on occasion im planning a trip to the beach and want to get it fixed before we leave thanks for any advice
