stock 02s

i have stock oems 02 sensors on my car and it has 123251 miles on it. Is it a good idea to replce them soon? Will i see better performance with new 02s then the old ones?

should I change all 4 or the 2 on the headers

yes you should change them

If your not getting any SES lights or poor gas mileage then dont change them however if you do get 1 or a few SES lights on your instrument panel blink on then take it for a free scan at AutoZone then decide from there. I asked the same question on this particular forum and got helpful replies to go that route. P1406 was my problem code and it was emissions related but not the O2 sensor. Turned out it was a flaky EGR. Replacing all 4 will run you big bucks if you check how much they are. Hope this helps you.

Either delete the post lol or see you in the For Sale forum, what color was your ride man? Sucks that you got totaled. I have a charcoal 5 spd interior, maybe you can offer parts soon like an ashtray assembly I'm searching for. Good luck in CamaroZ28.com bro...
