Front O2 Senors

[C|3R1C]

Sup Guys, Happy Fourth of July!!

I wanted to see if I could get some feedback on this little issue. About 6k miles ago, I had the bank 2 ICV and injector replaced on cylinder 3, and bank 2 O2 sensor (pre cat). Im running AA catless with a tune, but now I get the two primary O2 sensors malfunctioning warnings. both show up for few days, go away for a couple days, then come back. What could be bothering them so much? Btw I have 81,000 miles on the clock, so one sensor is way fresher than the other.

I had this same issue when I had the AA tune, talk to the guys at AA and they'll adjust it, It's related to a diagnostic on the O2 sensors, some cars do it some don't, something to do with the car seeing something out of range when decelerating. There is a fix for it.

Ahhh okay so it's the tune not being set a certain way. Thanks for you input on this!!

Pretty sure that's what it is, don't quote me 100% on it, double check with AA, they're pretty good
