slightly rough idle at initial start up
Hi All
I have a 2008 C 300 4matic with 120K on it. it runs great after its warmed up a little (like after 1 minute) but it runs rough when it first starts up ? a slight skip perhaps ? I found the car overfilled with oil a while back ,drained it then notice the idle at start issue. the car has been excellent. just want to catch something early if I can. seems to be an issue with the cold start only.
Any help on what to check would be great
Thanks
in advance !!!

Mine is a little rough at startup, very slightly shaky, but it does not need warm up. Drive it immediately I don't feel anything rough, even stop at the first traffic light waiting.
