Dies cold! Help!

The problem with the startup.

Since its cold weather, we have a problem with the startup.

Start the engine and speed when he dies, dies at traffic lights (I leave), restart the engine goes to a stationary and tends to die. We lack the throttle at low Speeds.

I can help someone?

I have a Fabia 1.4 MPI 8v, 68 hp, ATZ.

Seems like the fuelling is all wrong. The first suspect would be the engine coolant temperature sensor. The thermostats are also prone to breaking on these engines so for the little extra cost it may be worth getting a complete thermostat with temperature sensor. The part number for a thermostat assembly at a guess is : 047121111S.
