Testing the ignition coil

    I suspect the ignition coil pack or igniter or module on my friend's 1995
    Accent 12 valve engine for causing the hesitation problems. Is there a
    reliable way to test it for the somewhat common failure? Would testing them
    with a spark plug for a good spark be sufficient? If the coil is bad, would
    I notice a weak spark while cranking, or would I have to run the engine with
    one spark plug out?

    Nearly every test I do on these shows they're good unless there's no spark
    coming out. I'm to the point where if I think it's the coil, I go to the
    parts department, get a coil, then take it to the car and plug it up
    without bolting it on.

    Thanks. It ended up working fine after we changed the wires but I suspect
    the coil may be weaker than it used to be. Usually bad wires don't make the
    car run horrible, just a little worse.
