    I have just pulled all 4 ignition coils from my 2011 Prius 3 because of running issues. Two of the coils are OEM Toyota (Denso) and two are aftermarket crap. Now, I have read many tutorials on how to test on plug ignition coils but I am kind of mixed up because the OEM coils are giving me different readings then the aftermarket?

    Is this normal?
    Does anybody know what resistance ohm numbers I should be getting?
    Any other ideas?

    The problem is upstream, coils aren't your problem.
