Hello, I have a 2022 Uforce 1000 and barely use it for light chores around the house. Recently the check engine light came on and starting running rough. Scanner code is P0130 02 sensor circuit bank 1 sensor 1. I took it to a weekend mechanic and he replaced the oxygen sensor and fuel injector, inspected the wiring harness but it didn't fix it. Ideas?

Thanks.
