Sticky pots

I finally figured out how to simply solve a niggling problem I have had with the Metro for a long time. When the the car has not been driven for a day or more, when I first start out, the acceleration would be jerky. This is especially problematic for reversing, since it reverses fast. After I would drive a little while it would be nice and smooth. What I tried (and it worked), was to pump the accelerator pedal 20 times before turning on the car. Voila, smooth acceleration from the get go. So nice to solve this issue!
