ok so i got a header that only has 1 o2 sensor and my stock 1 has 2 im running check engine light and car idles like **** can i get another connecter and splice into the wires on the 1 and just plug it in or what should i do?

 

you should have one o2 in the header and the other coming out of the cat, unless your running a test pipe.

 

no he does not have one coming out of the cat if youre thinking of the cat underneath the car because only the ex/si have a seperate cat underneath the car. what you have to do is use your header and also buy a cat from a ex/si and run the o2 sensor back under the car

yes i'm well aware of this seeing as i just put a header on my dx. its just sounded to me he was confused where the sensors should go
