Remember that injectors have 2 components to failure, electrical & mechanical. The early, 90~92 are the most prone to failure as they do not have SS trim in the injector. Ethanol & water are soluble which translates into rust & corrosion to the non-ss trim.

What does this mean? Just because the resistance checks out, does not mean the injector is good. It just means the electrical component is OK.

Leak-down & flow testing are the only way to check the mechanical component. Best done on a flow tester.
