Did some searching and it turns out there was one other person out there with our
problem.

He had the terrible vibrations at high
speed once in a wild too.
Everything we've checked he's checked
the last post that I saw he was checking
the electronics. Like where the coils plug
in. That were I think lies our problem.

Update you if I find anything at all.

BTW, one of the last post even talked
about the connectin to the ECU!!!
Let's just hope it doesn't come to that.
