Cavalier wideband fluctuating

[chevy948]

I seem to be having a problem with my wideband o2 readings. at an idle and when cursing they will sit between 14.0-16.0, but when i floor it i get a constant reading at about 12.5. i cant figure out why its doing it i have done all ve tuning and even tried to add more fuel to the idle and had no effect on to it. im beginning to think that its a bad o2 sensor but i don't want to buy one if i don't have to.

I think your referring to what we call "PE Mode". This is 100% normal, its what you want to see. Although,if you are cam only, that's a little rich WOT. Post the log you have of this and lets make sure. Post your config file as well so we can see it as you do

Ok, that's your tune and log... can you post the config your using in your scanner?
That log is of idle only, post the log you have when you went WOT as well

Config file is the .cfg file you are using in your scanner to see your sensor streams. When you open your scanner, at the top there is a "open config" button. From there you can upload the file you are using to the site here.

Okay so i believe this is the file you are talking about

In normal driving the ECU commands 14.6. This can't be changed, but is perfectly safe. Once you go WOT (floor it) the ECU goes into PE (power enrichment) which runs off the tune. This part is what you tune it to.

1, What Wideband are you using?
2, What Hpt do you have (pro or Standard)
3, How do you have the Wideband connected to the HPT?
