I have a 2003 coupe 6mt, over the past couple of weeks ive been noticing when i turn on my car and leave it in neutral to let it warm up there appears to be a constant knocking noise that is extremely noticeable.. but when I get on the clutch the noise stops automaticaly.. but when i take my foot off It starts again, for the past couple of days ive been driving with the windows down in order to listen to the car.. when im coming out of first a hollow raspy note comes up throughout 1000 to 2000 rpm this also happends through out the bottom end of most gears its just not that noticeable as 1st And when i leave the car in neutral and turn it off there is a slight clunking before the car goes silent vs. when the clutch is engaged and the car is turned off... This is getting extremely anoying and I havent had time to go to the dealership. I would just like to know what you guys think soo i have a general idea of wtf is wrong with it... please give me your feed back. Thanks!
