The recently released video about the C4 ZR-1 that had Hagerty?s name at the bottom may have solved this. The speaker revealed that a second rev limiter was programmed in for cold starts all because a particular quality control female employee was starting up the brand new cars with her foot depressing the throttle 100%. This led to an engine failure or two during and engineering, after discovering the root contributor, decided to put in the second rev limiter. Hear about it from 13:00-14:15 in the Hagerty video. Given that my car is only exhibiting the behavior described in my first post until the engine has slightly warmed up I believe I am experiencing this described second rev limiter. I learned something new today. In general, this second type of rev limiter was not really implemented on main stream cars until about 20 years later!
