Hey, I am new into the forum. I have a problem of poor running. I have 1.3 multijet(jtd) and when I start the car, it starts well but it has approx. 10 seconds of rough idling. It sometimes stalls. It lights the check engine light for this ten seconds period but no codes are triggered. And the most problematic part f this is it only happens when I come to high altitude place(nearly 2000m or 7000ft). It happens intermittently but nearly all mornings. Sometimes with hot engine. Some say it's because of the software of ecu, some say its because of injectors. I don't think it's because of injectors because there is no black or white smoke and no poor engine power. Can be bad electricity or some?
Thanks in advance.
