If you got a wild engine, as soon as you've found out which one it is and you're capable of single engine flight, idle it, don't touch it again and find a nice runway to run onto. All the pissing around in the SIM that I've struggled with over the years to try and deal with the situation is more pain than it's worth. Fly the damn thing to somewhere safe and land. 100 miles out at sea yeah I know.
