Hey Doc,
I gave up on the Z-28... Its been to the dealer 3 times now (almost $1000) and they cant find the problem either. For some reason its EATING ignition modules. They have replaced it 3 times now and its dead again. Have you ever run into this before?
Just once bud, try disconnecting (or cutting) the tach lead right at the ignition coil, dump a new IGN module in her and see where that gets you.
Doc
