Hello all! I'm new here and I'm hoping to find out if someone has had similar issues that I'm having with my car and if there is a solution. I have a 2016 Nissan Maxima Platinum with 57,000 miles, recently the check engine light keeps coming on with O2 sensor codes P0171, P0172, and P0158.

So far I have taken the car to the dealership twice the first time they replaced the mass airflow sensor, and the issue came back, the next thing replaced was the rear O2 sensor. A few days later the check engine light turned back on with the same codes. The dealership is really taking all my money as their next solution is to replace the fuel injectors.


Symptoms:

Car will sputter as if its having a hard time to keep up while driving, earlier today my rpm was going up but the car was slowing down with no pressure in the gas peddle and I was forced to pull over after sitting for a while I was able to get it home.


Has anyone else had similar issues or know what I can possibly do to remedy myself?? Any help or guidance would be greatly appreciated!
