After KIA K3 started the fire, the speed needle did not respond and the throttle automatically increased.

There was no reaction after the fire. First, the oil pressure is unstable. If the engine carbon deposit has been cleaned, the throttle valve has been cleaned, the oil pad and spark plug have been replaced, and the car body still shakes at idle speed, it is recommended to check the fuel supply pressure and intake pressure sensors at the 4S shop.

After the fire, the accelerator is automatically increased after the gear is put into gear, because when the cold car is just ignited, the driving computer detects that the engine temperature is too low, which affects the work of the internal gear parts, and in this case, driving will hurt the engine parts. At this time, the driving computer will slightly increase the speed (generally not more than 1200 rpm) to make the engine enter the best state as soon as possible. In this case, there are generally two solutions. One is to wait until the engine speed returns to 800 rpm, which is commonly called hot car; The second is to wait for the speed to recover, but the front section should be driven slowly, and it is basically necessary to warm up when leaving the garage.
