It was a beautiful day today, decided to take the Charger out for a cruise. It would hardly run, ran really poorly, refused to idle and was sluggish to accelerate, even backfired a couple of times. Once up to speed it smoothed out fine. It had a 1/2 tank of gas when it was parked and I used Startron Gas conditioner. Today I filled the tank with fresh fuel, hopefully it will get better as I drive the old gas out.
