Question about Nissan Altima
The octane of the fuel is too low or the timing is too fast.
A code P0171 may mean that one or more of the following has happened:
* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
* There could be a vacuum leak downstream of the MAF sensor.
You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.

SOURCE: rattle when accelerating
had the same issue, had someone look and it seems the noise was caused by heat shield being loose covering exhaust system. Have that checked out.

I recently experienced the same symptom with my '05 Murano and it was not a fuel problem. The dealer listed the cause as dry axle splines and replaced both front drive shaft assy's. Note that this was done as warranty with no cost incurred by me.
