5 error codes at once
So the CEL came on yesterday and I had autozone run the codes. What came back was p0401, 2 p0171, and 2 p0170.
I have research what each one of these mean but what I was wondering is, what would cause all of these come on at once? Any help would be greatly appreciated.
So before I get yelled at about searching, I have research each one but need a cause for all at once. Wasn't able to find someone that has had all at once.
Thank you,

P0171 System too Lean (Bank 1)
P0401 Exhaust Gas Recirculation Flow Insufficient Detected
As commented above.
Also clean your MAF
