Engine doesn't want to run in cold conditions.

[Evo2driver]

Dear FTO owners,

The fto from my brother has a problem. He has bought the car also with this problem because we think it was a small issue but it isn't.

The problem is :

When the engine is cold the engine start and rev up and then the engine stalls. When you press the gas pendal a littlebid than the engine turns good. After she is warmed up the engine runs fine at idle.
We have already putted a second hands throttlebody with all the sensor on it. We have tried 3 different stepper motors, change the ECU, change the throttle position sensor.
I've put it on a computer from mitsubishi and see that if the engine is cold the temp sensor is also good and the steppermotor is also reacting. Even as the idle stand and the position sensor is working well.

We have checked a lot of things but still the engine will not run after a cold start.

I hope somebody here would help us to get this car back on the road !!

Regards,
Remco
