From my reading, your symptom is the classic one for needing
a new fuel filter, like HT Misfit wrote.

But if the fuel filter has never been replaced, what's the
status of the ignition wires, plugs, distributor cap, rotor,
and air filter?

These too are going to affect performance. Consider
replacing all of the above with new, genuine Honda versions.
Cost is about $100 for all the above ignition parts from the
online Honda sites, like www.slhonda.com . They are basic
tuneup items and need to be done every few years, anyway,
particularly if one wants the distributor coil to last a
long time.

Ignition timing should be checked as well.

If this doesn't improve things, then for a car this old, I
would also be a little suspicious of an old, worn oxygen
sensor aggravating things. They are not too expensive for
your car.
