UNPLUG the harness from the injector,BTW To remove the connector from the injector, push carefully in the middle of the locking clip, with your thumb, This will make the sides, and tips move OUT WARD in their connector slots allowing the tips that hold the injector into the connector to slide out of the way from the injector body, and you can then pull the sides away. WATCH the locking clip - IT can and WILL come off and get lost, if your not careful put your V.O.M. meter on OHMS and put the leads across the two connectors ON THE INJECTOR ,it should read about 11-16 OHMS in most cases, a few are designed to read up to 19 ohms, or as low as 9 ohms , The Ford motorsport injectors in the 24lb-hr flavor test a little lower (14.1-14.3 ohms) than the bosch's @ 22lbs/hr. (15.9-16.3) BUT ALL INJECTORS IN A SET SHOULD READ WITHIN ONE OHM OF EACH OTHER if its out of that range by a wide margin ITS MORE THAN LIKELY DEFECTIVE, checking the OHMS reading as a first step will frequently detect a defective injector, naturally using your trouble codes , a shop manual and a fuel pressure gauge won,t hurt and a shop scope , or engine analyzing software with a read out to your laptop computer helps and can further isolate the problem, at IDLE speeds placing a finger tip on the side of the injector will usually allow you to feel it (CLICKING) adding a couple cans of injector cleaner and about a pint of MARVEL MYSTERY OIL to a full tank of fuel can sometimes free a sticky injector that partly clogged, but don,t do it frequently as its very hard on the CATS and O2 SENSORS if done constantly
partly clogged injectors tend to reduce power and increase emissions

MORE INJECTOR INFO
"Most early EFI systems were batch-fire systems (TPI) where the ECM fired all eight OR BANKS OF FOUR injectors simultaneously. Usually batch-fire systems fire the injectors once per engine revolution. This way, the injectors could be sized small enough to be more easily controlled at idle. Later, sequential EFI systems were refined to fire an injector a few degrees before the intake valve opened. Generally, sequential injection offers more precise fuel control at the price of increased complexity. But on production engines, the benefits are more in the area of emissions and driveability than in performance".
Like all electrical devices, injectors have an internal resistance to the flow of electricity. The amount of resistance is measured in Ohms, or impedance. The higher the number, the more the resistance. Injectors are either high impedance or low impedance. It's crucial to get the proper type. While high and low impedance injectors may look identical on the outside and fit the same, if they are the wrong type they can fry your ECU, injector resistor pack, or other expensive parts. High impedance injectors are sometimes called "peak and hold" injectors, while the low impedance injectors are often called "saturated injectors." Make sure you get the right type. If you're not sure what you've got, you can check the resistance of your injector with a DMM (digital multi meter) set to measure Ohms. Saturated injectors have a resistance between 10-18 ohms and peak-hold injectors have a resistance around 2-6 ohms.
your corvette was designed to use the 10-18 ohm rated injectors
