Failing 15/50

high hc co and nox

need some suggestions. Im already going to run injector cleaner and top end cleaner to get some gunk out, and possible checking the map sensor.
Any other suggestions to fix the issue

i will also take advice on how to pass without having to initially fix the issue, but i would in the long run like to fix the issue. thanks

 

^I reduced the size of your image.

When HC and NOx are both high, one must consider the possibility of a bad cat.

 

First check and make sure your O2 sensor is working properly. If it's not. Then the Air fuel ratio will not be correct for the Catalytic converter to operate properly.

 

Thanks for reducing the image. I have a spare o2 I'll try in there and I hope to jebus I don't have to buy a cat. I'll keep trying stuff.
Bump

 

how come the report show up as a intergra if your car is a civic

 

I would assume it is because a Civic with an Integra engine is smogged (and must conform to the requirements of) an Integra.

This is assuming the OP had the car put through the BAR and the swap is certified.

 

i failed too they told me its my cat so i have not went back cause those cost to much

 

bump. i was hoping their were more gurus out there

 

yea they would just recomend a shady smog spot to bad your all the way up north could have helped you out ;P

 

out of curiousity how much does a new cat cost?
