Freaking P0171 P0174 codes

[Court X3]

Been running this down for about a month now and need some advice, light came on after getting gas, so first checked the fit to make sure it was snug, no problem.

Then started researching and trying to find easy fixes, so far have done the following:

Checked gas cap, cleared SES light came back one day later
Cleaned Maf, cleared SES light came back one day later
Removed intake boot, checked for cracks none found

waiting on:
Spark plugs
Air Filter (noticed mine had a tear along the edge, but don't think that would trip SES)

If that doesn't fix it, leaning on replacing the MAF
