Fiat Punto Turns Off if i don't give gas when im driving. When i turn i must give small gear to have many rpms, if i don't have many rpms, motor turns off. This problem is highlighted when the machine is hot.

Idle cause problems, as the gas, and may shut down. This problem is highlighted when the machine is warm.

The car has been renovating the timing and replaced the thermostat, and all have been successful. The machine does not heat up any more pin. Timing belt does not cause this problem. Also, I noticed that the difference between idle is a cold to a warm 150-200rpms

as the machine stifling gets too little air, and it might be too rich on gas..

check temperature sensor, it may be still telling ecu engine is cold when its really warm
