Hi i have a 2001 eclipse gs 2.4L automatic. It makes a terrible sound while idling in drive or reverse. It is worse when it is cold or wet and is a very rare noise in the summer. If anyone knows what it might be that would be great help. A youtube clip of the noise is below. If link doesnt work please search "2001 eclipse idle noise" on youtube.
