How do you know when you have a bad injector and how do you figure
out which one it is?

A bad injector will usually cause a miss, or rough running. A field
check is to run the engine at idle and loosen one injector pipe
connection at a time. Loosening the connection on a good injector will
cause the engine to miss or run rough. Loosening the connection on a
bad injector will change nothing.

However.... Injectors can be set at the wrong opening pressure or have
a defective spray pattern that may not show up using the above check
and can only be found by removing the injectors and having them tested
at a shop that specializes in repairing fuel system components.
