It was my JJ-1400 at that you saw Shok. Soon as I know what exactly it was I'll post it on the this board. Most likely a failed RPM sensor or the Fadec.

So you got one!
The RPM sensor is easy enough to diagnose. Spin the turbine with the ECU on and see if it reads RPM.
What exactly is happening? Beware of some of the advice given out, don't do anything just yet.
