So I have a 1991 Integra, Automatic Transmission
My check engine lights been going so I checked whats wrong and my ECU is throwing codes 12 and 43, I think the code 43 is my o2 sensor, but what would be the fix for code 12?

 

Anybody know what parts could be causing the probem for code 12?

 

I'm not sure about 12. But I think 43 is a fuel related one. I have a chart with all the check engine codes on it. I'll put them up here tomorrow

 

I found out what 12 means but I don't know what part to go at to fix :/ tried searching but no avail
Here is a list of the codes are for the 1990-1991 teg's

bump for help

 

Um, if you're getting 12, you need to check the EGR.
All this stuff is in a Haynes manual: $10.

43 is usually a fuel pump issue, but can sometimes be caused from faulty injectors also.

 

Thanks, I've been meaning to get one. Only got this car two weeks ago, and its my first car :/
