Looks like I got me some grounds to clean!

For grounds I use non insulated crimps.

I will take a look at it and clean. I don't remember ever cleaning it and my engine bay gets grimey with oil + dust.

By chance do you recall where the ECU ground point is? I think I remember it being behind the passenger's side kick panel but I might be mixing it up in my head with something else.
