1.9 D keeps the speed of switching short to high

Hello, since no one in the Fiat Forum gets in the right way, I try my question here. The following: I have a Strada 1.9D year 2002. This drives without any problems, only when switching he holds the rotary zal too long up so that there are more shift trucks in the lower gears. This is especially annoying when you turn on a parking lot and then kick the clutch to hold on. Or when you drive over a parking lot and then kick the clutch. People look then Always, as if you were too stupid to drive because it still holds the driven speed for about 2 seconds. If you give gas in the stand it reacts a little delayed so probably with the gas acceptance and also gas removal. If it is cold, the problem is rarely present. Does someone here perhaps have an idea how to turn off the behavior?
