Greetings, got a small issue (atleast i hope). 2013 1.4. Whenever I fuel up, the car has trouble starting. It cranks for longer than normal, even after i let off the key. Eventually starts but then idles really crappy. After I pump on gas pedal a lil it comes out of it and runs good til the next fuel up. I've also had the engine not shut down when turning the key off on one occasion(About 4 minutes after fueling up). These issues are only on fueling up. Kinda strange. Any ideas? Thanks
