Default Mercedes C270 Juddering????

Hi I wonder if anyone else has had this problem and can help he diagnose the problem.

When my car is started in the morning, it fire's up perfect but the idol on the rev counter seems to bounce, not fast just up and down a fraction? The idol will go down like it is about to stall then pick up again to normal but it will do this constantly? When I drive to work which is 25 miles away it seems to clear itself which I am finding rather odd?

One person said to try injection cleaner which I have? Then I took it for a full service but still seem to have the problem? I called the person who done the service and he said it would be the Coil???? Now this is when I thought I would ask you experts first!

So if you can help i would really be appreciated!

Thanks

Jason

it sound as if you have an automatic choke problem mine does somthing similar but only when i have had the battery on charge but after a few miles it goes away take it for a tune up as services dont check for these problems and see if that works tell them first what the problem is you may have a small leake in the manifold or some thing daft like that
