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?

Actually, my Integra's factory shop manual shows it under a section called
"Fuel and Emissions".
