O2 sensor question

First off I'm o. The mobile app do in unable to search at this time. So my issue is when I'm driving my car my bank 1 will intermittently lean right out and fuel trim will be 0 while bank 2 is fine. So I want to know which o2 sensors I need to buy for bank 1. On ecs tuning it tells me they have for rear left and right but does the rear deal with bank 1 or bank 2 any help would be great

Thanks

You are going to want the pre-cat O2's, as that is the one that measures lambda values.

Ordered both front o2 sensors from ecs tuning so hopefully it solves my problem

It hasn't yet but I watch my Afr closely. But when it leans out and I try give it gas to see if it will come back it just hesitates and sputters and barely accelerates
