i have a 95 civic lx 4dr and i put a b16 in it. i wired the vtec nd knock sensor, but when i drive around for like 1/2 hr i get a c.e.l I checked it nd it gave me a o2 sensor code. the motor came with DC headders nd it doesnt have the sensor... any help plssssss

 

Add the sensor. Weld a bung on the header. What's so hard?

 

Why in the hell would the header not have a bung for an 02 sensor? Doesn't make sense.

 

my bad. im not a mechanic or a welder. how do i do this? drill a hole in the hedder nd weld it in?

 

wow

 

no don't do it yourself

take it to a muffler shop

 

or buy new headers since DC is garbage anyways.

 

A header without a bung, man that must be garbage, yes get it done professionally and do it the right way first.
