I had a cel pop on, on my 99 civic si. i checked it out and it was catalyst was below projected threshold then i clear the code and it doesn't come back on for about 6 months. After about another 6 months it would come back on. It doesn't sound like the o2 censor is going out since it doesn't come right back on. It is the bank 1 o2 which means its the one in the header. But it does have a GReddy header, Jackson Racing Hi-flo cat, and EVO2 cat-back, could that be it? Any ideas?


And how long do i have to be a member before i am out of the trial user bullshit? only 5 posts a day sucks!
