Which injector is bad?

My second original injector is starting to go bad. Overfueling and making some smoke constantly. I'm trying to change it out myself, but need some guidance in how to test to see which one it is without pulling all of them.

I know Ford can buzz test them to find out, but is there anything I can do?

You need something like AutoEnginuity that will run a cylinder contribution test.

Shouldn't it throw a code?

The first that went out a few months back made it smoke like a freight train and it never threw a code. Crazy!
