I ran my car low on fuel one day. I stopped at a local gas station and put $20 worth of gas in my car. The gas was 100% gas ethanol free. I believe it was bad gas. My gas mileage dropped drastically and the car started to spit and sputter. I have replaced one 02 sensor, the fuel filter, fuel pressure regulator, mass air flow sensor, and the spark plugs. I am still having problems with the car spitting and sputtering and having a lot of exhaust, white, come out the tail pipe. I stopped at auto zone one day and I have a cylinder 1 and 2 missfire. Any ideas what may be causing this?
