The sedan Sega cold car is not easy to start.

Judging from the phenomenon you described, it is difficult to start when the car is cold, and the idle speed is unstable, which is mainly caused by excessive carbon deposition in the electronic throttle body. Sega uses an electronic throttle body, and the throttle of this car is sensitive to carbon deposition. If there is a little carbon deposit on the accelerator, the idling will be unstable, it will be difficult to start or stall during driving. Therefore, it is suggested that the car mainly improve the shift speed, and it is best to shift gears between 2500 and 3000 rpm to avoid idling in place as much as possible. I hope my answer is helpful to you.
