I was on the highway when my cel, check vsc light, car with squiggly lines came on. I used a scanner and got only one code p0171. Since the code is only for one engine bank I feel like it would maybe be the upper o2 sensor? I already cleaned the maf sensor since that’s easy but no joy. The fuel trims for bank 1 looks bad but I don’t know the normal values for the other pid’s. I’ve attached the freeze frame, any help would be appreciated!
