I put a known failed misfiring coil on the test bed next to a brand new one this morning and all ohm readings were identical
Sometimes, yOu have to part swap

Re: coil test thread - coil on plug resistance measurements 30713416 9125601
Do you have any method to heat the coil while testing? This would more closely match operating conditions for a coil. I don't know what temperature on top of the head would be, but at least coolant temperature.
