What could I do to fix this? I got a 12 and a 43 code on my ECU. I have a 90 Integ with a reprogrammed ECU for a 1st gen B16.

Code 43 is fuel supply system
You sure you get code 12? Better count again.
I checked this last night and these were the codes based on slow blinks followed by rapid blinks. I checked out what the codes mean, but I don’t know how to fix them. There might even be more codes but I doubt it.
CODE 43 AND CODE 12
Code 12 is EXHAUST GAS RECIRCULATION; check the hoses, the EGR valve lift sensor and the system EGR valve.
Code 43 fuel supply system usually the oxygen sensor, however check fuel pressure regulator and check for vacuum leaks.
Hope this helps.

ONE MORE THING
I’d strongly suggest getting a Haynes manual. It shows you how to do basically everything.
5 speed tegs dont have an EGR valve. Only autos
Helms says if your throwing a code that doesnt apply to your model your ECU might be bad.
Is your sled auto?
Used to be. Now I drive in park all day.
lol
Start with the o2 sensor, and go from there.
After you change that out, see if you still got 12.
If you had someone to trade ecu’s with for a minuite, that would be a good idea too.
Ok cool thanx. I’ll start with the O2 sensor. The one that connects to the headers right? And my friend has a 94 Integ, stock and manual, will that fit?
