Might be a leak on your brake booster (this will most probable give you a hard brake pedal or a "sucking sound " when applying brakes) also check the vacumm pipe from the engine to the brake booster. It might have a leak, so when you press the brakes it influences the air mixture.
I will have that checked to be sure but i have no sounds like that or a hard break pedal... My friend said try to switch out another sensor the throttle position sensor i just hate to keep trying one after another and putting out so much money. Its really annoying first start of the day lol. But thank you and i will have that part checked out too cant hurt
BBest suggestion take it to a Nissan dealer sn that they can do a diagnostic. A problem like this can be so many things. Ignition coil, HT leads, sparkplugs, faulty or poorly conected sensors etc. On my fathers Audi A4 it turned out to be the Lamda sensor. (Car sounds like an old datsun on a cold morning when you start it in the morning) And yes a lot of people will replace one part after the other until the car works and you will have to pay for their trail and error.
Well the last place that replaced the first sensor at $300 plus i hadnt even left the parking lot and told them the propblem wasnt fixed, they have put it on all kinds of machines, and no codes pop up.... but i told them i paid to have it fixed and its not so they kept the car another day and changed the mass air flow thing..(without asking my permission first) at $180 which still didnt fix the problem so he refunded the $180....but i will take your advice and try to go to the nissan dealership and go from there everything points to the throttle position sensor now that ive done more research and all of the "symptoms" my car has, but i mentioned that initially and they changed everything but... go figure lol. thanks for the advice and i will get all of these things looked at just to clear my mind and fix trhe problem. thank you
So what did it turn out to be eventually?
My Maxima acted the same way until I had the Idle Air Control Valve replaced.

I have already had the mass airflow sensor and the idle air control sensor change with no help
