RB 211-22B engines were prone to this at low ambient air temps - saw this many times.It was usually accompanied by slow acceleration to idle or a hung start with low egt. Never saw it on Tristar or 747 with any of the -524 series engines - the VIGV and FCU systems were different. A newly installed engine will also do this while burning off inhibiting fluid in the fuel system.
