If you have SU HIF carb(s) it could be caused by a faulty poppet valve on a
throttle
butterfly. These open under decelleration to reduce pollution and should be
closed by
a spring before the engine gets to idle speed. There's not much you can do
with them
other than to solder them shut or replace the butterfly with one without the
valve.
