I had this code checked out and it said runing lean on bank 2 and I was going to change the O2 sensor to see it that would fix it but because they are so expensive, I dont have the money to replace both of them. So I was wondering can I just change the O2 sensor on the bank2 side and be ok? I have the 3.8l motor.

 

i have the p0174 and p2198 i'm going with the o2's
