It sure would be nice if you turned quoting on.
Your Code 12 means the EGR system is not responding correctly. This can be
due to quite a number of things, especially at your car's age.
Several possibilities:
1) EGR valve carboned up & EGR valve not lifting correctly;
2) Valve lift solenoid not operating correctly;
3) CVC valve not operating correctly.
You need to obtain a copy of the Helm manual, which gives detailed
troubleshooting for the EGR system. I think I have an Accord shop manual
from that era somewhere, which should be close enough. You'll need a vacuum
pump (Mity-Vac).

Re: the old PGM-FI thing - i have 87 honda prelude
Your site has been tremendously helpful, Tegger. It led me to some
shop manuals in PDF format. i can't remember where exactly i found
them but they are quite helpful.
I don't know yet if they mention the EGR. They are scanned images
rather than text so I can't search them...just have to keep looking
through the 1200+ pages. Where would EGR be? Under exhaust? Engine?
Carb? Emission control?
Also, do you think that my stalling problem could be related to the
EGR? I am having this problem where the car loses power dramatically
when i'm accelerating with the engine around 2500 rpm. It's as though
it were running out of gas. Then as soon as I push the clutch in
and/or take it out of gear, it idles just fine. The problem also
doesn't seem to occur when the engine is not under load - I can rev the
car just fine when it's not in gear.
The PGM-FI troubleshooting table suggests any number of things could be
the problem when you have a lack of power at lo/mid/hi RPM
* faulty ecu
* fuel injector open or short circuited, stuck injector (they do seem
to be leaking)
* faulty fuel pump / fuel pump relay OR poor grounding
* improper fuel line pressure OR clogged fuel filter
* manifold absolute pressure sensor - open or short circuited, broken
or disconnected hose, faulty sensor
and none of those seem related to EGR, do they?

* faulty fuel pump / fuel pump relay OR poor grounding
* improper fuel line pressure OR clogged fuel filter
* manifold absolute pressure sensor - open or short circuited, broken
or disconnected hose, faulty sensor
and none of those seem related to EGR, do they?

Classic sign of an EGR valve that's carboned up and sticking open. Your
Code 12 is telling you the ECU is seeing incorrect lift heights from the
EGR valve.
It is possible to disassemble the EGR valve and clean out the carbon by
using a drill bit (held in your fingers) to gently clean out the holes in
the valve diaphragm.
It's likely your whole damned EGR system is choked with carbon, including
the passages in the head.
Somewhere there's a TSB that shows how to unclog the EGR valve, but I can't
find it just now. Help anybody?
