P0171 code, cleaned MAF then got a P0174 temporarily?

The P0171 code specifically points to a lean condition

Since the cleaning fixed it for a while, I would replace the MAF sensor because once the sensor is too far gone cleaning it will not help to will also cause low power and gas mileage. Here is how to change out the sensor correctly. Check out the images (below). Please let us know if you need anything else to get the problem fixed.

By these readings I would replace check for vacuum and exhaust leaks and if there none replace the sensor. Also, you should check the fuel pressure, here are guides to help you:

Use this guide when the engine is cold only:

Key On Engine Off (KOEO): The fuel pressure should be approximately 60-66 PSI. (Pounds per square inch).

Key On Engine Running (KOER): The fuel pressure should be approximately 55-62 PSI.

You can rent the gauge at the local auto parts store for free or cheap. Please go over these guides and get back to us.
