High STFT

[Brians6]

Took this log after turning SES light off, for the following codes

[ECM] P0174 - Fuel Trim System Lean Bank 2 (SES) (Old) (History) (Immature)

STFT B2 gets near 40% after frame 1049 and then i kill it. Wasnt even going to attempt driving around like that.

Why is it doing this? All i did by unchecking that SES box was too turn off the light right? Then why is my STFT going all apeshit.

Im pretty sure the o2 sensor is bad and the only reason i am messing around with the SES light is to pass the visual part of smog.

Here's a log i took immediately before turning the light off,

Ok, turned it on and let it idle for awhile, the stft seemed to level after a bit. Ran like crap for the first few minutes though.

Do you understand the difference between LTFT and STFT?

Take a look at the LTFT. What does that tell you?
