Have been getting CEL and "tighten fuel cap" recently on dash.
Today I went to fill it and it did not want to take fuel. It was empty and the nozzle kept shutting off. ( FYI, I have a tendency to overfill, round up to nearest dollar)
As I filled, I could hear air or something unusual come out of fuel tank.
