But when I plugged the connectors back in, the marble sound is still there, but substantially reduced. But I have a feeling that changing the solenoids isn't the issue of the marbles in a can noise because it still present.
Its the tune and specific firmware...I had this issue with newer maps on the Procede...Went back to older maps and noise was gone..
