so i recently had a crackle pop tune, i took it off after running it for a week. I don’t have a catless downpipe and i took the time off 2 weeks ago. The other day i had a check engine light pop up so i scanned the code. it was for the o2 sensor bank 1. My ST doesn’t backfire anymore like gurgles and when i shift then accelerate into 2nd gear, the car shakes back and forth a bit. Does the o2 sensor affect the cars performance?Im currently running no tune and i still haven’t changed the o2 sensor.

Many have had similar problems, and yes, the o2 sensor effects performance. Sensor 1, Bank 1 is the wideband.

I suggest a KAM reset and to keep an eye on the AFR. If you receive another DTC referring to the the wideband O2 sensor (sensor 1 bank 1) then you may need to replace it. This sensor is crucial to your vehicles operation.

Was that your only tune or did you switch to another tune without the old poops & spackles? Who is your tuner?

So are you stage 0? I would advise against running one of the more advanced stages from Cobb as they are more of a base for you to build from using there tuning software. Not a beginner sort of thing.

Bank one is the front O2 sensor which monitors your air fuel ratio controls how the car runs bank 2 is the rear O2 sensor just to tell the car that the cat is working. Bank 1 o2 sensor will definitely affect how the car runs you need to change that.
