500 nevertheless, remains accelerated to the gear change

[pippo65]

Hello guys I need your opinion.

I have a Fiat 500 1.3 multijet 75 cv, which is a bit of time, especially from cold when I change gear remains accelerated

then warming up the problem disappears.

I have cleaned the sensor of absolute pressure,the flow meter but the problem remains.

Diagnosis there are no errors and all the parameters seem ok.

what could be sensor,the clutch pedal?

Thanks to all for the advice.

Hello, the machine is ori or mapped ?

[sergiot]

if the car is original (or if mapped well) check the clutch switch, might be perfectly calibrated, and not to mark that the clutch is pressed.

The machine is ori,do you know if there is a way to test the switch on the clutch pedal?

[sergiot]

with one hardware settings serial diagnosis. or with a multimeter on the contacts, it is a signal, open closed.

are you sure that it is original,it is usually when they are wrong protectors

Also the manifold intake manifold clogged creates this phenomenon..
