So i just installed the skunk 2 racing headers on my 2004 RSX and the check engine light came on. I put on the o2 sensor adapter that came in the box for the check engine with 3 full rotation twists and tightened it and the light came on after the second drive. So i got under there and twisted it on all the way i could and tighten it. The light turned off (i was so happy) then it turned on again on the third ride... help!

This is what it looks like tightened all the way

It will go off and on and usually on. It recognizes no Cat and is telling you so. Some have better luck than others but it really tells you how well the cat is working--which it isn't.

Are you planning anything for your ECU? Ktuner has a flash designed for intake / race header / exhaust that will add power, improve your power curve and eliminate the 2nd O2 sensor.
