Hi everybody,

Just bought a 92 400E with 200K km, and found this wonderful website.

This is my first Mercedes, I love it very much, it handles so well at highway speed, I feel sooner or later I will get a speeding ticket

However I am experiencing some strange problems when I kick down at highway speed. It happens when I want to experience its acceleration at highway speed, at 120kmph, if I floor it, it downshifts as expected but as soon as rpm reaches 5000, I feel that engine bogs down and car actually slows down, if I keep gas pedal floored, it will get into a kind of oscillation: bog down and come back, car just shakes back and forth violently.

Has anybody experienced the same symptom? Does this just mean air filters, fuel filter or plugs need to be replaced? or some serious power train problems ?

Thanks.
