It makes a weird noise that sounds like its coming from maybe the flywheel/clutch area but I'm not sure because it does it when I'm driving. Sometimes it is at idle, but mostly under acceleration, especially at low revs in a higher gear. Slightly concerned since I just got it three weeks ago. Confession, I first noticed it after I forgot I was in gear and dumped out the clutch with the brakes on after I had just started it in a parking lot. First stick shift so I didn't think about those things for a while. Any ideas? Also, my rear end sounds a little clunky between shifts, is that common on these cars?
