Ok, I can't figure this out and asked a couple of "mechanics". Here is my problem. I have a 2007 dodge caravan. It runs fine, except right after I fill the gas tank. After I fill it, if I stop at a red light it will stall. When I am driving I fill it kind of loosing power. This will continue until I drive a couple of miles, then it will run fine again until I fill up again. Any one experience this?
