Hi guys
I have the dreaded rough idle issue or so I think.....!!!!
C200 CDI, when started from cold it starts on the button no problems...then bout 10 seconds in it develops what I can only describe as a miss.....its intermittent and not consistent ????
So maybe not really a rough idle but a very annoying problem...
This can then sometimes be throughout the day...there's no real pattern to it..
My first thought was a misbehaving sensor of some sort, but not sure ???
P.S. No lights on dash, no other warnings...nothing !!!

So any advice would be much appreciated guys.....!!!!!!!
