Super rough idle lights flicker

So my 2017 trax has 50k miles on it and about two days ago I really noticed whenstopping the car shimmys and shakes hard and when I fill the tank it has a really hard time fully starting. When idle it has almost like a chug feel to it. Ran codes and it was telling me that i have a fuel bank lean error. It seems all that can go wrong with this car it's happening alall at once. Hallllp. Lol

P0171 is a lean code for bank one and P0173 is a lean code for bank 2 which is odd since a 4 cylinder only has bank one. So I would start by checking for a leaky intake. Check boost, clean MAF.

What causes the P0173 code?
A dirty or faulty mass air flow sensor.
Leaking intake manifold or torn intake boot.
Vacuum leak
Faulty fuel injector
Faulty fuel pressure regulator
Pinched fuel line
What are the symptoms of the P0173 code?
A Check Engine Light
Increased smog or soot from the exhaust
Loss in acceleration
Hesitation or misfire during idle
Increased fuel consumption
How does a mechanic diagnose the P0173 code?
Visually inspects the mass air flow sensor
Tests the resistance of the mass air flow sensor and circuitry with a digital multimeter
Performs a fuel pressure test
Inspects the wiring of the fuel injectors for fraying
Inspects the intake manifold and vacuum lines for leaks
Uses a scan tool to specify the fuel trim out of range (short-term or long-term)
Common mistakes when diagnosing the P0173 code
Replacing the Mass Air Flow Sensor without cleaning or testing it first

Deeming a component faulty without checking for more common causes, such as vacuum leaks

Not using a scan tool to determine if there is an issue with either the short- or long-term fuel trim

Failing to inspect the wiring of the component thought to be at fault

How serious is the P0173 code?
The life of the catalytic convertor could become shorter because it will have to filter more pollutants in the exhaust gases

Gas consumption will increase
