There is a gas smell in my Z every time i refill the tank. Its almost unbearable when I first open the car in the morning after I've topped off the tank the previous day. The windows dont work also, so its just a problem. I end up driving aroudn with my car door open. for the first minute or so. Does anyone know what this might be? I don't even have a clue where I should even start to diagnose this problem.
