Should Palio remove the throttle when cleaning?

Relax, the car can't be repaired. You should have cleaned the accelerator outside, and then this problem appeared. Did the staff of the 4S shop remove the throttle and clean it again without removing it? I suspect that it was installed when washing the throttle outside, and the other is that the vacuum tube was not inserted correctly.

You'd better go to the 4S shop. It may take a long time to get them a cold train. This phenomenon is called idling. Many cars idling may not be a throttle problem. When disassembling the idle motor, it may be installed incorrectly or the cleaning agent may enter the circuit, which may lead to the failure of the idle motor and throttle position sensor, especially the idle motor. At the same time, it is necessary to use a computer to observe the data flow when the fault occurs, and check the target speed, throttle opening and air intake. The number of steps of the idle motor and the concentration of mixed gas determine whether the fault is the target speed error or the fault caused by the computer adjusting the idle speed due to the signal failure of the actuator or sensor, so it is not a big problem to find an experienced master to do it seriously, and tell the pick-up consultant to find a better master.
