got on expressway, punched ecellerator to speed up. It did at first but then it felt like I was losing power. When I got off express. it was running with a bad miss and gas smell. Changed plugs, wires, cap, rotor, fuelfilter. still misses. When idling fuel smell, when taking off after idling a bit you get white smoke out the exaust. Any help please
