i have a 90 civic lx, converted to 4 injector.
running pm6 ECU for a SOHC ZC ENGINE.
i keep getting code 20 and 1 (ELD AND O2)at the same time. and when the CEL's hit the car instantly runs like ***. and when i park the car the exaust smells like straight up fuel. im assuming this is from the 02 code forcing the injectors to run pig *** rich.
i also have a brand new NTK O2 i just put on a couple of weeks ago.
ive been looking for hours on google , and i literally found nothing.
the one thing i did see on the web is that my main fuse box under the hood supposedly has no ELD.and the only si's or EX's had them. and i need to change my 2 injector fuse box to a 4 injector.
the strange thing is if thats true, would i CONSTANTLY have a ELD code since theres no ELD??? i only throw this code every once in awhile. its not like it happens everyday. it will do it for a week, and not do it again for months. and it seems liek it does it on VERY hot days.
and where exactly is the ELD in the fuse box? can i see it physically in the box?
would it force O2 code as well?
thanks for any help!!!

Hey man. I've been searching the web for a while and I just came across this post. I'm having the exact same problem. Did you ever figure out the issue? Sorry to bump a thread that's 3 years old, but I'm in real need of a solution!
