Code PO172 & PO175

[Colabella7077]

Banks 1 & 2 running rich. I turn off the engine light but it pops back up. I cleaned the intake filter and it stopped for awhile. When I start the truck up in the morning and occasionally after it has been running it idles at a high RPM, just below 1,000. Drops when going into another gear from Park. any suggestions?
-Lower Intake Gasket Leak
-Dirty Injectors

Mass Air Flow Sensor is a brand new Jet MAF. Had it installed in August and has been great. I don't think this could be the issue.

Why would a MAF set off these codes? it doesn't make sense why there product would do this if they had knowledge and It's not like I can return it. I had a feeling it was the MAF...
