Why is the car idling unsteadily when the air conditioner is turned on? The air conditioner is off and everything is fine.

Hello, this usually happens when the car is driving at a low speed for a long time, which leads to excessive carbon deposition in the engine, insufficient combustion, white smoke, engine jitter, reduced power, too fast speed, sudden flameout and increased fuel consumption. It is suggested that the engine, throttle and spark plug should be cleaned, and the power will return to normal after matching and debugging.
