Spring breeze 150nk cold car can't afford to refuel.

1, throttle and air flow meter have too much carbon, and they are still easy to get dirty. Nowadays, most cars are electronic throttles, and a little carbon deposition may affect them. Too much carbon deposition in the throttle will cause the valve to jam when filling, the power will drop seriously and the idle speed will be unstable.

2, cylinder combustion chamber, piston carbon deposition is too much, cylinder combustion chamber carbon deposition is too much, it will have a certain adsorption effect on gasoline, so the ignition time will be extended a little. In addition, too much carbon deposit will be formed on the valve and piston ring, which indirectly leads to insufficient cylinder pressure, and the cold car is easy to idle and unstable, but it is good to warm the car.
