I don't know how you can DIY test an injector... you'd have to look at spray pattern and volume of fuel delivered I'd have thought.. not DIY friendly.
It does sound like a shot injector. Your best bet is to try and pick up a second-hand injector and see if that sorts the problem... The affected cylinder would be running rich by the sound of it.. so you don't necessarily need a full set of 4. If you have an obvious duff one, then leave the s/hand one in there (or buy a new one for that cylinder, depending which option you prefer).
No bullets for Chaingun..
