It is normal for Wei Zhi v2 cold car to idle at 2000 rpm.

Not normal. When the cold car is started, the rotating speed should not be too high, because the oil has not yet reached the part that needs lubrication, and too high rotating speed will seriously wear the engine. Wei Zhi v2 cold car idling at 2000 rpm, the engine is hot because the throttle is stuck or the sensor signal is inaccurate, so you can go to the 4S shop for inspection and maintenance.
