I can't see the picture, but I wish I had seen this post sooner.

I would have offered a few suggestions, none of which involved buying a new optispark, especially not an MSD.

What is the issue shown in the picture?

The tach bouncing around almost always means a hi or lo voltage condition...is your alternator bad?


The picture is of spark plug wires with the insulation gone ware they were touching the headers. The tach bouncing around started before this. I just took it out for a test drive with a new opti and new wires its running good now. I did not notice if the tach was acting up just went for a quick drive.
