Hi All, I am new to 204, I maintain my 99 slk 90% of the time, of course with the help of the group, I just purchased 2010 C300 4matic, with 138K miles runs very nice I love everything about the car everyday i find more and more fun things that the car has, I notice when I stop at a red light the car idles rough, but when I put the gear in neutral idles smooth, any advise would be very appreciative I must have done wrong search, could not find any case like mine, I am hoping some of the experts here would lead me to the right direction. Thank you in advance

Thank you for your response, I will check to see if the mounts are bad.
