    Hi everyone!

    I seem to have a slight missfire more noticible durring highway driving. I have replaced the plugs, wires and fuel filter. Pcv seems to work fine. I checked the coil resistance quickly today durring my lunch and they all had simmilair values but one pack was lower than the other two. I was wondering if someone could tell me what range they should generally measure out to? Or if anyone has any other suggestions. Thanks!

    the test specs are 0.5 to 0.9 ohms for the primary terminals under the coil, and secondary resistance of 5,000 to 8,000 ohms at the high-voltage terminal.

    Should they be checked with the car running or off?

    To check the primary side, they have to be removed.
    Oh, and if you want a 30,000 volt shock you'll never forget, ya check them with the car running!
