OK, here is the run down....90 teg ls with b16 swap,450cc with T.E. i listened to my injectors for the clicking and only one isnt clicking as fast as the others but is still clicking.is the injector dirty or maybe the resistor box fouling on that injector?

 

resistor box issues shouldn't foul a single injector.

move the injector to a different cylinder, see what happens. if the problem moves to that cylinder, it's the injector. if not, it's the wiring/ecu.
