I am still looking for help with my benz running like it has water in the gas. I have put water remover in the tank and it still will run great driving into work ( about 15 miles) and when I go out to get breakfast 30 minutes later it runs and boggs down, picks back up, when I stop it does it again. If I turn the car off it runs like new again. It is almost like when it gets warm it does this and it is not good to be scared to pull out into traffic when you don't know if it is going to stall or not. Any advise is greatly appreiciated.
