Hi Michael,
I jdrove my Healey across the country (Canada) back in 1979. I had an interm=
ittent mis-fire all through Ontario., then it cleared up. When the car quit c=
ompletely in Alberta, it turned out to be the rotor, but like your experienc=
e, it took a while to diagnose. This would have been an original Lucas rotor=
=E2=80=A6.so I guess they sometimes fail intermittently, like a coil, making=
 the process of elimination quite difficult.
