The codes are saying bank 1 and 2 are running lean. it runs rough and if u get in the throttle it acts like it is starving for air

If you're experiencing a rough idle in your 2011 Nissan Altima, the first thing you should do is diagnose the issue. The Torque app can provide you with some diagnostic codes which can help you narrow down the problem. In your case, two current fault codes and two pending fault codes were recorded. The current fault codes point to a system that is running too lean on Bank 2 and misfiring in multiple cylinders. The pending codes indicate a system that is too lean on Bank 1 and a cylinder 2 misfire.
To start troubleshooting, you should begin by checking the spark plugs and ignition coils. Both of these components are integral to the proper functioning of the engine. If they are faulty, they can cause misfiring and rough idling. You should also inspect the mass air flow sensor, as a faulty one can throw off the air-fuel ratio of the engine.
Finally, if the problem still persists after inspecting the spark plugs, ignition coils, and mass air flow sensor, then you should consider consulting a professional mechanic for further diagnosis. They can provide a more accurate assessment of the issue and recommend the best course of action.

Definition of Diagnostic Trouble Code P0171 Category: Powertrain Definition: System Too Lean Bank 1Note: This definition of P0171 is applied to all manufacturers

Clean your throttle body and map/maf sensor. If that doesn't work you may have a bad iac sensor (idle air control sensor)

P0171 System too lean bank 1
P0174 System too lean bank 2

Last time you changed your fuel filter?
Look for any vacuum leaks.

Mass AIR FLOW ( MAF)- sensor contamination......

P1131 Lack of HO2S-11 Switch ,Sensor Lean
P1151-Lack of HO2S-21 Switch ,Sensor Lean
PO171- System to Lean (Bank 1)
PO174-Systen to Lean (Bank 2)

Fuel Filter -Plugged
Low Fuel Pressure
Evap System -Leaks
Leaks - in ducting,air filter to throttle
PCV -Leaks
Exhaust System -Leaks
O2 Sensors-worn out

PO 134 = 02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 1 SENSOR1)
PO 153 =02 SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 1)
PO 154 =02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 2 SENSOR 1)
PO 155= 02 SENSOR HEATER CIRCUIT MALFUNCTION (BANK 2 SENSOR 1)
PO 171= SYSTEM TOO LEAN (BANK 1)
PO 174= SYSTEM TOO LEAN (BANK 2)
I WOULD SAY YOU HAVE FAULTY OXYGEN SENSORS CAUSING THE ENGINE TO RUN TOO LEAN REPLACE THEM AND YOU SHOULD BE BACK IN BUISNESS

Yes but its very unlikely that both 02 sensors went bad at the same time.

If youe engine is starving for fuel, it will run lean, have no power, and set these codes.

You arent running e85 fuel are you? That stuff sucks and most vehicles do not run well on it.

I would check the mass airflow sensor to make sure its not dirty, check the air intake tube to make sure its not cracked or out of place, and then test fuel pressure and volume.

I suspect a fuel issue of some sort. ( pump or filter etc) Its kind of hard to say without looking at it myself in person.

what year/make/model mitsu are we talkign about here?

LOOK AT THE MASS AIR FLOW SENSOR.WHEN THEY GET DIRTY U WILL HAVE BOTH BANKS LEAN.CLEAN ITAND CLEAR CODES
