I have an 04 3s 5 spd and it’s recently started making this intense rattling or chattering sound when accelerating. It’s most prevelant in 1st and 2nd gears between 1000-3000 rpm although it can happen in any gear at any rpm. It does not happen in neutral. It seems to be coming from the passenger wheel area. I’ve done some research and it may be a motor mount? It doesn’t sound good, however, so I wanted to see if anyone had any ideas. Thanks
