Engine "stumble" coming to idle.

96 900SE, 101k miles, manual.
Noticed the other night coming to a stop at a light in neutral that the engine would slowly loss rpm's down to idle (~1,000rpm) then kind of stumble to abut 800 rpm than go back to 1,000. The car runs fine at any speed and there is no hesitation from standing start. The only mod is Dawes device and it was tuned up about 8,000 miles ago.
It was about 40F and raining. With A/C in Auto, it was marginallly worse than with A/C off. Quick check of vac lines didn't reveal anything - they all "look" fine.
Didn't noticed it over the weekend.
Question: Is this indicative of an impending failure (DI cassette) or is it time to tune-up (new plugs) again? SHould I investigate further or forget about it?
Thanks, in advance... Rob
