Hey Flat,
Remember seeing you say that you added some pressure to brushes by pushing on contacts.
This is usually a good thing to do. Often it helps. When doing so try to keep contacts as flat as possible or parallel to chassis floor. If an angle is created it is transferred to the spring and then brush. Resulting with a brush tilted to one side. And less surface contacting comm plate.
While additional pressure may help. A better seating of brush along with additional pressure will help more.
With the rear of engine compartment being higher or deeper than the front portion on 4g's. Making the rear brush slightly higher than front is needed to get equal pressure on comm by both brushes.
I've come to believe a slight stretching of springs to be better. But brush heights are different and sometimes just changing brushes will work. All is experimenting.
