Hey, at least the colors matched But I'll have to get the car on an elevator to check both sensors since I have no access for now. I'll keep you guys updated. Thank you for all your help!

 

I started her up again today and this is what I got. I don't know how to interpret the first error but the second pic doesn't look all that changed from the previous videos

 

That code means the circuit of your upstream oxygen sensor is broken. However you installed it, it is not correct. That explains why it's not learning fuel trims, but I'm confused how it shows AFR at all. Perhaps the connection is intermittent, or the sensor isn't passing some diagnostic routine the ECU runs.

I'm betting heavily on the wiring splice

You can learn more by googling the error code

 

Thank you! It's clear I have no idea what I'm doing, even splicing color-coded wires I'll take her to an auto-repair shop, maybe they can sort this mess out.
