I'M having trouble with my 02 since I took off my catalic on my s2k. I changed the 02 sensor twice and the light is still coming back on. Is that normal on a s2k ? cause on my integra, civic, accord.. etc it never does that !

 

You have a test pipe, correct?

If you have a test pipe, you will have to use a anti-fouler plug in between the o2 sensor and the o2 sensor bung on the test pipe.. what this does, is it pulls the o2 sensor out of the direct stream to allow for a different reading of oxygen than the o2 sensor in the exhaust manifold. That is what the cat does, it burns elements down and therefore changing the amount of oxygen that it reads. So to make a long story short, the cat's o2 sensor has to read a different oxygen level than the one in the header. If it is in direct air stream in the test pipe it will read the same level of oxygen as the one in the header..

 

You bought 2 new 02 sensors?!

As Envied says...

 

thx a lot ! I just ordered it

 

I still have a problem, I did what you guys told me to do and it's now I have the code 1.
