Xeno,
The solenoid coil resistance is only one test of the injector, and says absolutely nothing about how the injector flows, the spray pattern, or even if the pintle is moving (opening) at all.
Bosch injectors (originals) are serviceable between 16½-11½ ohms without placing an unnecessary current load on the switching transistors in the ECM.
Multec and Rochester injectors are servicable down to 8½ ohms. Lucas injectors just plain aren't servicable (they aren't a very good design, and should probably be replaced anyway).
Your 16-ohm injector might be in great electrical condition, but could be completely plugged or mechanically binding/worn to the point of no operation, regardless of the solenoid.
If you have a complete set of used injectors, you might consider sending them off to {url=http://www.cruzinperformance.com]Cruzin' Performance[/url] for evaluation, cleaning, and flow matching. It's a very reasonably priced service and will remove any doubts.
