I have a 97 Civic DX Coupe with a D16Y7 and my stock header (cat built in) has a crack and leak, so I'm putting on a aftermarket one on so I can drive it, my question is It has 2 o2 sensors on it (one before the cat and one after) the aftermarket header I got has 2 ports for them but how can I overcome the check engine light that will come on when I replace it, I'm on a buget so I have to wait a few weeks so I can get a new cat and exhaust with my tax return, I'm not looking for performance just want a daily driver.

Thanks in advance

 

you need an o2 simulator in place of the 2nd o2 sensor

check ebay

 

You can make your own simulator buy using a couple of anti foulers.

 

You can get the non-foulers through ebay as well. They usually run about 10 or 11 bucks shipped.

 

Do you think I can get them at a local auto parts or hardware store?

 

You can ususally get them at a local autoparts store

 

What is an anti fouler? Pic's or links?
