Ran completely out of gas last week - put gas in - car started fine- ran a little rough and idled rough. Now 10 days later MIL light on in dash and perform service message. Won't go out after several

Have the fuel filter changed and have the computer checked for codes incase something else is going on and they can be cleared to turn off the light.any dirt in the lines should be out of them by now.its possible that there is dirt in the injectors and a fuel system service should be done to clean them which is a recomended service on all cars anyways.you can have the fuel pressure checked while its in the shop to make sure the pressure is within specs.
