Double Back

Was talking this week about an "experience" I had, long time ago when still F/O on the B747 200-300 series, that is with a F/E for the magenta drivers.
Our 200's were equipped wit P&W engines, and one of the features it lacked was the automatic fuel heat, besides having no auto throttle!
During cold nights the F/E was kept awake by this more or less continuous monitoring.
On one occasion he must have dozed off because suddenly the engines started to accelerate beyond the cruise power lever setting we had selected. I grabbed the handful of throttles to stop the movement and the now wide awake F/O immediately switched on the Fuel Heat which solved all.
I cannot remember why the engines accelerated and not roll back because of the forming of ice crystals. Anybody a clue?
