so i just got done installing my new front o2 sensor after it went bad when i installed my new turbo and since then i had also installed a wideband.


When the o2 sensor was still bad it would run anywhere from 10.6-11.9 at idle, and at wot it was at a safe 10.8-11.0

Now that it's fixed, what should my A/F's be at idle?

thanks

 

mine are mid 14's at idle and 11.6 to 11.8 at wot...

 

mine cycle from 14.6-15.2 at idle, and 11.4-11.1 at WOT

 

exactly same thing for me

 

same here

 

At idle and off boost your a/f ratios should be hovering around 14.7 . When engine braking, it should go very lean but when accelerating it might richen up a little. But in the end as long as your not WOT or in a lot of boost, it should be around trying to reach the 14.7 target.
