simes Posted July 9, 2008 Share Posted July 9, 2008 hi, I have an intermitant rattle on my Disco 300, Somebody has told me that it sounds like an injector rattling. Do they rattle. What causes it? How do I fix it. Do I just ignore it? Simes Quote Link to comment Share on other sites More sharing options...
