1 Injector has 17 OHMS, other 7 have 3 OHMS?
A friend lent me some un-used 30PPH Injectors because I was running out of injector.
After installing them, The engine missed on 3-4 cylinders. I Put the Old injectors back in Im on my way... But out of curiosity I tested the 30PPHer's, and 1 had 17 Ohms (normal) but 7 of the others had 3 OHMS... What is the DEAL here?

Just found out that the 1 injector that is reading normal is a different P/N than the others.

Sounds like either the other 7 are bad or simply low impedance injectors meant to be used with an aftermarket ECM, like DFI or Commander 950....
I would check the part # with the manufacturer and find out...
