        I used to Own a 02 spec V. So i know exactly what you are going through.
        You should be able to pull the service manual online for that motor some where
        inside there will be specific values for resistance and consistency for the coils
        you can individually measure them with an volt meter.

        Or you can swap them around and see which coil follows which cylinder.

            Should I replace all the ignition coils? Or should I just wait for them to go bad individually. I figure if one went bad, the rest would soon follow.[/quote]

            I would replace them all at the same time. It’s just like with spark plugs and usually with anything that has more then just one of the same part on the car you should always replace them all at the same time.

                    I don’t think you should replace them all. One of the main reasons is that most Asian makes don’t like aftermarket ignition parts. I’d wait and see if you end up having an issue. If you don’t then I’d call it a win and move on.
