Change the wires, and check the ignition coils while you're in there.

I had ignition break up during higher RPMs. When I checked the ignition harness it was in awful shape...very crispy and brittle. It appeared the rear trailing plug was rarley firing...not sure about the others. After replacing the harness the break up went away.
