P0133 and surging

P0133 - 02 Circuit slow: My SVT surges real bad and then throws this code. Has been happeneidng ever since it has gotten warm in CT. Going to do some datalogging today, but could the surging cause this code or is the 02 sensor causing the surging?

Ive been having P0133 problems lately also. It seems it happens when the weather changes during this spring. It might get 70-90* for a week, then the weather drops down to 40* and the 133 pops up. Then the MIL goes away after 30-40 miles until the weather cycles again.

I've been feeling some very minor surges, but nothing crazy. I'm pretty sure it's a bad O2 sensor causing the surging and code.

Did you ever get it figured out? Mine does this too. But only when it is hot outside. 90 degrees plus?

If you have a tune I would contact your tuner with a datalog and he can correct this

Does it with tune and with stock tune. My logging and tuning software is not here yet. That is why I am doing my research prior to getting my software.
