    What causes have been identified for a Peugeot 407 /2005 150.000 km gasoline engine (2.0) idle stall for cold engine?


    The car starts normal. But when put to idle in the first 400 meters the engine allways stops for the first ride of the day. After the stall the engine starts normally and never stalls after that for the remaining of the day working perfectly for the rest of the day. This only happens when the car has been outside for the night and the temperature is below +10 centigrade. This never happens when the car has been in a warm garage for the night. This never happens in summer when temperatures are higher. No error codes are triggered. All digital tests pass perfectly. Software version 12/2010 (latest). Carburettor unit changed. Both 5% and 10% biofuel used with no effect.


    Any ideas?

    Possibly the Intake ambient air tep sensor giving incorrect value after startup.
