What is your question?
I have a 2011 Nissan Altima that has been throwing a code stating there is an issue with the mass air flow sensor. We replaced it, and are still having issues. It doesn’t always happen, but when it does, the service engine light will be on (which that part is always on for some reason) and then the traction control light will turn on, and you can hear the engine doing a type of low revving sound. But if you put it in park, it stops. When I start to accelerate, once it hits 2500 rpm it loses power and starts to jerk.
What makes this problem better or worse?
Accelerating makes the problem worse
How long has your 2011 Nissan Altima had this problem?
A few weeks

"Issue with the mass air flow sensor" could be that the information read is out of range or of concern, or the circuit could be a concern, but is not a direction to replace a part. Testing is required. What are the diagnostic trouble codes you are reading? What test equipment is being used to monitor air intake, fuel trim levels, emission control components, ignition spark and timing, fuel delivery? There needs to be actual testing performed. A workshop manual for your Altima is essential in guiding testing and providing results. www.repairpal.com/repair-shops
