Help! P206 engine stals when cold

    Hi everybody, I have a problem with '05 peugeot206 1.1L and a little help would be appreciated. Engine cuts off when I start from cold. I have to keep the foot on the accelerator until the water reaches 80'C otherwise it simply cuts off. Once the engine is warm the problem is gone. Computer diagnostic finds no faults, i replaced all temperature sensors(off the other 206), put in a new stepper motor and every other sensor available but nothing helps. I believe the stepper motor doesnt get the signal when to retract cos when i start the car it extracts, turn off the engine-it stays in the same position, start again-it extracts further more and on the 3rd attempt it simply closes the air intake and the car doesnt want to start. Any ideas what might be the problem?

    When did you last change the spark plugs?

    replaced that one too but it made no difference. Of course there is a chance that some sensor i've replaced might be faulty as well but which one? Somehow I suspect the coolant temperature sensor might be the case. Checked autodata troubleshooting-almost every sensor in the engine bay maight be the problem...lambda somehow isnt listed.

    Strange that the diagnostics found no fault.Was it a main dealer that did it?
    You could end up changing every sensor in the engine and still have no joy.
    Bring it to a reputable mechhy or a main dealer and pay for them to tell you whats wrong at this stage it will end up being cheaper.
