That data looks normal.
To go back to your original complaint, it was a loss of power on a hill and idle vibration. The idle vibration is a known issue that as far as I know cannot be fixed. For loss of power, you could have a fuel flow issue, air flow issue or compression issue in the engine. I would monitor the OBD2 data while driving up the hills you have an issue with and see if the data stays within normal bounds or starts to strongly deviate.
Maybe you are getting transient fuel flow issues and the earlier trim data was correct. Nex time while you are monitoring, swap scanners to confirm the other one is indeed bad.
There are plenty of internet articles on causes of loss of power. Like this one https://oards.com/causes-of-a-car-st...-going-uphill/

Apologies. What is your MPG on the highway (include your typical driving speed) and city driving?
I normally get around 16-18 for city driving and 20-23 on the highway. Typical highway speed is 70-75 mph. Those are real mpg calculations and not the car computer.

Also, I just tested my cheap scanner, I think it is just false readings, it keeps cutting on and off and I have to restart the car and app, but it was a litte better readings than before. Also, I was trying to test the air/fuel sensors like in the video above, so I created a vaccum leak, I put the hose back on, but could that be the reason its different? Should I reset the ecu in the car?
