I have a 2005 Mustang V6 with 1600 miles on it. Tonight I filled the gas tank and after about 15 miles the fuel tank gauge went to empty. The low fuel indicator light then came on. Then the check engine light came on. Within a minute the fuel tank indicator went back to full and the fuel light went out. The check engine light stayed on. The car seems to be running fine. Anyone have any ideas on what is wrong??? Thanks!
