Codes P0171 and P0172?

Here is what is said about the codes:

The codes P0171 and P0172 refer to a problem with the fuel mixture in the engine.

P0171 is a "System Too Lean (Bank 1)" code,

P0172 is a "System Too Rich (Bank 1)" code,

The fact that it goes from to rich to the lean I need to ask of the exhaust system is in good shape no leaks. If so, is the engine misfiring? Can you upload a short video of how the engine is running? If everything is okay, I would replace the primary oxygen sensor. Here is the location, Check out the images (below). Please let us know what happens.

Everything seems to run okay. Same as it always has since I got the car in October anyway.

Okay, because the system goes from rich to lean, I would replace the oxygen sensor (primary).

Here is a guide to help walk you through the steps:

Just wanted to respond now that I feel safe with the answer. I replaced the air filter because it was pretty gunked up, and then cleaned the MAF sensor. I cleared the codes, and it seems to be good to go.

Thank you for your help!
