My 93 EX automatic has over 200K miles on it, I am recent nth. owner,
car runs perfectly but only gets low 30's with careful suburban
driving.

Based on experience, what one item would you suggest replacing that
can have an immediate positive impact on fuel economy?

Thanks in advance !

Tire pressure.

Here is a long list, grouped by approximate cost:

A lot of this one would do in the course of a normal tuneup.
You do not know exactly where the car is in its maintenance,
so if you have the bucks, you might next want to start with
a tuneup.

apart from all the usual maintenance items, look at the tw sensor. even
though testing showed mine to be "in limits", replacement took my civic
from 31.8mpg up to 36.2mpg.

i only really spotted the difference because i have two cars essentially
the same - civic and crx, both automatic, same engine, maintained to the
same standards, even same tires/tire pressures. crx was in the 36's long
term average, civic as stated. oil always got dirtier quicker on the
civic too and it had a problem warming up in cold weather, even with two
new thermostats. finally concluded it had to be the sensor, and hit pay
dirt. was totally convinced when i went to my local junkyard and
discovered that there was hardly a honda in the place that still had a tw
sensor in it. someone, somewhere was switched on to this problem some
time ago!

it's a thermistor used to measure the coolant temperature - "tw sensor" is
its honda technical name. it even has "tw-5" stamped into the brass screw.
