I put a b16 sirII in my 92 civic and I've had a CEL the whole time I've been driving it, for like a month now, I just put in a knock sensor and that still didn't help. So I was wondering if anyone knows how to read codes that would be great. Then I can finally figure out exactly what the problem is. My engine has been running in "safe mode" and I'm tired of it, any help will be greatly appreciated. I have a 92 cx and I think that the 02 sensor may be hooked up wrong. Maybe thats the problem I don't know. I just need to read the code, thanks
