RPM Surve when cold
 

Problem: I get rpm bounce aka idle surge when the car is cold until operating temperature. When the car warms up it idles perfectly. The car has just been tuned and there are absolutely no symptoms when the car is being driven after the warmpup.

I just changed the TPS sensor and it's controlled through the fcon v pro (engine management), settings are good as far as I know.

And the year of the car is???????????????

it's a 91 S5
