i just installed borla headers on my 2.5rs and two days after my check engine light came on, what could be the problem? do i have to mess w/my s-afc?
i tried to reset it by removing the battery, it went away but came back on the 2nd day again??=(

 

Same here, I did searches and figured that we need to wrap our headers and it goes away. Something about exhaust temperatures. Read somewhere else that the sensor in our cat is not a temp sensor, but a pressure sensor and the loss of pressure before the cat (due to headers) is triggering the cel. I don't know if it helps, but searches help a lot.

 

thanks alot man! did you wrap your headers already or you put back the stock manifold?!

 

hey guys sorry to jack the thread but where did u guys get ur headers?

 

thats the way it is blazer the code will more than likley be for cat inefficency(sp?) when i put on my borla header it did tha same thing it would go away for a month or so comeback on and go away again i just learned to live with it
