You mean P1857? No such code on Hondas.
DTCs are one letter and four numbers. You have an extra digit in there.

Uh-oh. Coolant was being pushed out but could not go back in again. Very
very bad.
Is the hose from rad cap to reservoir cap intact?

A lot of people. So long as the car keeps running, they keep driving.

Is the thermostat aftermarket?
When the engine is overheating, can you make the temperature decline by
turning on the interior heater and fan full blast? Or do you need to rev
it to get the temperature down?
Does it overheat in heavy traffic? When idling? Anytime?
Specific details on the exact nature of the overheating will help in
diagnosis.

Recheck that code number. It's formatted incorrectly.

OK. Finally got to change the thermostat and coolant in this car. It
still overheats. I'm pretty sure its the head gasket. All I did was
start it up and drive up on some ramps, turned it off and when I went
to open the rad, it was under a lot of pressure. So I'm guessing that
exhaust is getting into the coolant. The old coolant was pretty dirty
as well, and the coolant resevoir kept filling up, though it never
overflowed that I could tell.
Not sure if I want to tackle a head gasket on this car... any
pointers? There's a guy down the road from me that works at an Acura
dealer and fixes stuff in his home shop on the side. Gonna go talk to
him to see what he thinks...
thanks

definitely sounds like head gasket. you can do it yourself, but it's
not for the faint hearted or inexperienced. you'll need some special
tools as well.
that said, i recommend it if you want to save some money and enjoy
working on your car. allow /plenty/ of time - this is not a quickie
job. or alternatively, price simply replacing the motor with a low
mileage used one from japan. the economics are very competitive.
google this group for some write-ups on doing this job. and one more
thing almost no shop will ever tell you: avoid getting the head skimmed
if you can possibly avoid it. almost all shops skim as a matter of
course because it makes /their/ job so much easier, but it's bad for the
head, [it's never finished like the original and so starts to leak again
after a while] and it slightly alters both the cylinder compression and
valve timing. the head won't be warped if it wasn't over-heated, and
it'll clean up ok with judicious use of spray-on gasket remover and a
fine blade scraper. do NOT use abrasives in the cleaning process. they
end up residing in the cylinder, wearing the cylinder wall and rings,
and wearing out your motor double-quick.
the write-up in the honda workshop manual is the best you can get.
