Sure you can drive it but if it starts to miss don't drive it!! I'm doing 2 engines right now cause they drove them and melted pistons and cylinder walls!!
Yes there is a update for this code but I've only seen it work as a patch for a few weeks or so then the trucks come back. The trucks that came back ended up needing high pressure pumps and if you get metal dust from 1 and 2 on the both rails with coffee filters you will need all the injectors...
