Failed emmisions!
#21
[quote=bbarbulo;17457]. is the car modified at all? is it running Y8 injectors by any chance? (Y7 injectors are smaller than Y8 ones) how much history do you have with this car...
The car is bone stock with the exception of suspension. As far as I know its running y7 injectors. As far as history with this car is concerened I just bought it off of a relative a couple of weeks ago. I do know it was sitting in a field for a couple of months this winter but thats it. Thanks for the replies everyone. Good lookin out.

most times failing all readings is an indication of a cat problem. true they don't fail on their own. burning coolant, oil, running lean etc. most of the civics I've seen with failed cats are due to a crack in the exhaust manifold. it looks like someone blew a torch though it.
I think it sees air in the exhaust causing the o2 t read lean thus adding fuel. extr fuel + air in the manifold = hot. or it runs lean causing a lean misfire which sends unburnt fuel and air down the manifold. not 100% which one.

Update!Passed emissions with flying colors. I had the injectors tested and one of them wasn't firing properly which resulted in raw unburnt fuel coming out the exhaust. I had it cleaned, put a new Magnaflow Hiflow cat on, added some Methyl alcohol(gas line anti freeze) for good measure to the gas and she passed without issue.
