Stilo 1.2 16v rev problem

[Alien]

At the last technical control in the 1st month when the controller study eco-test he could not keep the motor rev still, I do not know how exactly 2500 rpm I guess. Somehow engine revs rise. I tried the same thing myself it was the same. The controller asked me did in the driving engine goes in revs? My answer was no, the ride is normal and I have not noticed anything. Idle is normal, rides as always and nothing unusual I can't notice. Since the new technical approaches have somehow solve problem. I tried it today and it is same. I press some throttle, just how much would be enough to keep the engine at 1000 rpm and with the same amount of throttle engine begins to rev until about 4000 rpm. I also noticed that the problem is with the warm engine. When engine is cold everything is normal. Multiecuscan did not found any errors. Is there someone who met with such a problem?

To eliminate problem of dashboard first try to connect mes and your stilo (engine ecu) and compare rpm on the dash with the one in mes.
I they are the same then it is not problem in dashboard (which can happened).

Probably it is some kind of mechanical problem.
Since you are from Croatia you can research fiatisti.hr forum.
They should have infos about your problem.
