Why does my Car start after I fill up the gas tank?
When I fill the gas tank up, the car has trouble starting. It happened several times already. I would then try for a while until I start it up again. After that, the car would run fine until I fill the gas tank up the following time. I went to a shop for this but they couldn’t fix it. Do you have any idea why this happens? Thank you.
