hi Mike6412,
I do not believe there is any adjustment possible on the throtle. I have the same problem but you get used to after a while. One tip that I have found useful is when stopped put the transmission into the manual mode and it should indicate 1st gear. Whilst stopped push the lever forward and it will go into 2nd gear even though you are stationary. You can take off in the gear which will be smoother and this will prevent the wheels spinning.
Once moving just push the gear level back into auto mode.
This tip is actually in the owners manual supplied with the car.
I assume your car is an automatic.
cheers, John
