Mass Air Flow Sensor Problems of Nissan Altima

Something happened to the mass airflow sensor where it limits the rpm and slows the car down a lot almost made a accident happen I took it to my mechanic he told me it was normal and I would have to take it to Nissan to get it fixed but that he sees that a lot.

This was a used pre-certified car, purchased from the dealer in which did not have any issues until its warranty was practically no longer valid. The cars electrical system started to have issues. The issues with the electrical system started with the usb port connection to a cellular device. Sometimes the car will recognize the phone, other times I have to disconnect the usb to phone connection, turn the usb cord around and reconnect a few times for the radio to recognize the phone. After this issues, one speaker went out. Later on, a second speaker went out. I replaced both speakers to find out that it is possible the in-car amplifier blew. After this, the radio unit would at times go completely black, causing me to have to turn the car off and back on. After this, the driver side door no longer locks electronically, I have to lock and unlock driver side door manually but the passenger side does indeed work. After these issues, I noticed the check engine light had come on for a mass air flow sensor. I cleaned the sensor, and the engine light went away. About 300 miles later, it came back on and the car hesitates/bucks consistently with a loss of power once the speed hits about 60 mph. I-75 hills, I can no longer accelerate to maintain speeds. I replaced the maf sensor, check engine light is still on. I had it cleared from o'reilly's since the same code was appearing on the car. After 10 miles sitting in idle, the traction control sensor appeared. 10 miles afterwards this on I-75, the car will not climb hills, drops power, bucks and jerks the car forward and back. I stopped at a part store, turn the car off and back on. Traction control sensor goes away, engine light comes back on with same code reading. I cleaned the throttle body, check engine light is still on. I've read a lot of articles about this, no one has figured out how to fix this.

The power outlet in the center console had gone bad so my husband changed the fuse and as soon as I started to drive, my car started jumping and would not go over 15mph. The traction control light and check engine light had both come on. I turned the car off for about 30 seconds then cranked it again, the traction control light was off and the car drove fine. Now at random times, usually if the car is left idling, the traction control light will come back on and the same thing happens but if I turn the car off for about 30 seconds then crank it again, the light is off and the car runs fine again. The mass air flow sensor was replaced in 2017 but that is the code we keep getting when it is hooked to a computer. The transmission was also replaced in 2017, no issues with it so far. . . No one seems to know what is going on with my car but it's pretty scary when I'm driving with my 3 kids and the car decides to lose power, jump all over the road and only drive 15mph. This happens at least 3 times a day and since this is my primary way of transportation, I would really like to know what is causing this issue so it can be fixed and I can safely transport my children again.
