i added a 4-1 header system with high flow cat converter and high flow cat-back exhaust. i have the 2nd o2 sensor after the converter but my check engine light wont go off now and when i go into autozone they tell me that i have improper readings from the o2 sensor. any help on how to get the light to go off is appreciated. ohh and i had to extend the wire on the sensor to get them to reach the hole in the line.

 

So the noob needs to be introduced to the search button. It is red and it is in the top right corner. Noob meet search button , search button meet Noob.

I will give you a clue.... defouler and search in the 01 -05 forum.

 

i dont know what you are talking about with the defouler but if you just tell me where the topic is i would appreciate it because ive had enough running around over this thing and i need to pass inspection asap. thanks

It is just that I hate to give out info about this kind of stuff. Being in the business that is trying to stop this sort of stuff.

If you do the search do it for defouler in the civic 2001 to 2005 forum and do the search in the post bodies. Don't mess with the rest. There is more info in there for you.
