I just had my car tuned... literally a a week ago. When they tuned it they told me my O2 were "lazy" and to replace them, so i did with bran new Bosch O2 sensors. 90miles later it's throwing the O2 sensor codes again.
Bad parts?
Any thoughts?

Also.. This car has no cats, LT's through to a 3in Y into SLP Lous Mouth.


Thanks,
Ross

 

What's the code number?

 

Ha... yeah that would be something i need... I didn't get it... I just went to the local Auto Zone..
I just remember "Bank One Sensor one" and " Bank two sensor one"
Ill go to my friends shop and have him get the code for me. Hes got the Snap On scan tool. I wont be able to get it until Friday though.

Thanks for the quick reply,
Ross

 

Do you have long tube headers? If so this is a very common problem due to the 02's not getting hot enough to function properly. Many have changed 02's only to the the problem return (even the Bosch vette 02's). Easiest fix is to turn the code off (set to not reported).

 

If i turn it off, will it effect they way the car runs?

 

Nope. It should no longer throw a code. When it does throw a code, it switches to open loop and runs rich.

 

Yeah, I can smell it!
Thanks guys
