flow test will show a restriction and DVM will show if they're working

Dvom will show if they are firing but if your running rich, it wont show you a leaky injector. Youd need a scope for that which hardly any backyard mechs have.

Check the ohm readings of each one if you haven't yet.

Look in a good Fi manual for an "Injector Balance Check", this will tell you if one is plugged.
