Could anyone tell me what the highlighted wire/connection is?

I have an intermittent misfire that sometimes triggers a limp mode/EPC fault. Tearing my hair out trying to identify where it’s comming from ( not injectors or coil packs)

The highlighted wire is intact but rusted

I found these type of interdental teeth brushes to be perfect for cleaning out connectors.
