clk 230 k jumpy start
 

Good evening, not sure if this is the correct place to post this but here goes

I have just acquired a w208 with an problem when you put the car in d and pull away from cold the best way i can describe it is the same as pushing the accelerator too hard and the car "jumps" it changes gear smooth and runs well when hot it pulls away smooth any ideas.

Problem is similar to you jabbing your foot hard on the accelerator pedal

thanks
