I have been having some issues. I have a 2006 Dodge charger 2.7 V6 with 155,000 miles on it. Starting two weeks ago my car started to stutter while giving between 50 to 75 percent throttle. Now my check engine light came on saying P0158, high voltage circuit on bank 2 sensor 2, now I replaced both down stream O2 sensor. After clearing the code and went on a drive, still proceeded to stutter but no check engine light until yesterday on 10/14/19, what other things can it be?
