Re: testing injectors

Get an injector testor, pulses the injectors while you watch fuel pressure drop. But if the car runs smooth at a steady cruise speed at light throttle, runs good at full throttle, and starts easy after a couple minutes after shut off when hot, the injectors are probably good.
