    I would test them, just because a couple have failed does not mean the rest will. Test them and fix only what is broken. It would probably be a good idea to replace the spark plugs if they exceed 60,000 in mileage while you have it apart. Ron.

    your issue is likely not a coil; the plug wires get soaked with oil from the valve covers. you can buy the plug wires
    individually as needed.
