    I would suggest comparing the resistance between them with an ohm meter.
    Give a man a fish and he will be fed for a day. Teach a man to fish and he will promptly forget that he once did not know, and proceed to call anyone who asks, a n00b and flame them on the boards for being stupid.

      Wow, that's a GREAT page. Really makes things clear. Now I'm certain on how to rebuild a fuel injector.

        The coils in an injector seldom open up, so an ohm meter probably will not tell you anything. What happens more often is they get clogged or sticky, and don't spray properly. A cylinder balance test may tell you something. Moving the injector to another cylinder to see if it moves the problem is a good way to tell. If its sticking open, you'll have a darker plug on that cylinder. If one isn't spraying properly and going lean you'll have eithe a really white plug or possibly other signs of increased heat.
