The Coupe’s Issues are mostly sorted out, but it has a rather scary periodic issue. At high speed, like in the fast lane on an interstate, the car will periodically stutter. Correction, it is more like an abrupt cut in fuel or ignition, than a stutter. Correction 2, I cannot say that it would not happen at low speeds, or at lower RPM. I also cannot intentionally reproduce it. As you can imagine, this is pretty disconcerting at 80 mph. The diagnostic trail will start with a fuel filter, as I have no reason to suspect ignition, and it should be showing up elsewhere in the rev range. We shall see…..
