My 2011 w221 has what I can only describe as a very very light jitterish feeling when I make very slight adjustments on the throttle.

Cruising along at say 30mph if I let the accelerator pedal go altogether it feels as though the throttle is delayed when released slightly then as though it is applied and released a couple of times, it is almost un noticeable but the sensation is there.

Same when applying throttle back on slightly, feels as though it is applied, released and applied again.

I guess it almost feels like a misfire but the sensation is the same when applying and releasing.

Has anyone else experienced this? I am assuming it is to do with the fact that the throttle is electronic and cannot apply it as smoothly as a physical cable could..
