Has anyone else spent years with a Z3 with the feeling that the car has an irritatingly heavy accelerator pedal? Do you get the feeling that the car feels strangely heavy, sluggish and reluctant to accelerate despite having plenty of power? I did for 100,000 miles - then I changed the throttle cable, and suddenly the car was transformed - light, responsive and agile.

Well worth the investment. Give it a try...
