Well, you win a few, you lose a few...I replaced the coil in my car...NOT
the problem. I mean, the coil did need replacing, but it wasn't causing the
tach to jump. So I am learning the hard way to go with my "gut" and not
think things through too much. At first I was sure it was the ignitor, but
thinking about it too much made me think it was the coil. I appreciate all
of the info from everyone...I have a new ignitor on order now...hopefully my
problem will be solved as soon as I replace it. BTW, my car has been
running progressively worse. It "misses", hesitates, and almost backfires
now...*sigh*
