Check engine light?

Sorry he's ill. However, we need the actual code numbers. There are multiple items tagged as bank 1 and 2 that can cause the light to come on. With the codes it should be possible to narrow it down a lot.

You are welcome. We will be here.

Okay, those are opposite codes. The P0171 is too lean on bank 1 while the P0172 is too rich on bank 1. At the moment the codes are saying that one side of the engine is getting both not enough and too much fuel at the same time. What I would do first is to erase the codes. Then drive it and see which one returns first. If the scan tool can read live data, you could look at the high and low fuel trims as well as those that would show which was happening first. I would suspect a possible vacuum leak. With the engine cold it draws in extra air and sets the 171-lean code, the control system keeps adding fuel. Then it warms up and the leak closes and now it is running very rich and starts to remove fuel but sets the 172 rich code.
Fuel trims that get better as the throttle is opened would point at a vacuum leak. A smoke test on the engine when it's cold might show the leak as well.
