Place a flat head screw driver on the injector (while the car is running) with the metal part on the injector itself. Put your ear against the side with the handle. This will act as a stethoscope. Repeat the process for each individual injector and you will hear the injector click or open up.

The one that sounds like it might be "stuck" - while the car is running, tap that injector on the outside (lightly), it should free up the injector.

They were new but now i've used them and i'm fouling plugs like the car is dumping fuel eventhough the 02 says its lean so i'm going with maybe an injector sticking but i took the whole rail off and turned the key on and i dont get any leaks i would think if its stuck open wouldn't it be coming out cause it doesnt close all the way
