According to the structural principle of the measurement and control system, this type of fault phenomenon described by your good friend should be caused by the abnormal adjustment of the idle motor. If it is still impossible to replace the original idle motor, first carefully measure the working state of the idle motor, plug in the idle motor, start the vehicle, and observe whether the idle motor has corresponding adjustment function in this state. If not, then we need to consider overhauling the engine computer board and idling motor drive module, because its failure phenomenon is very obvious, and these aspects are only basic inspections, and then we need to consider further checking the influence of fuel pressure. If the fuel pressure is abnormal, it will lead to too little fuel injection from the fuel nozzle, and the air-fuel ratio will turn off when the load changes. Therefore, it is very necessary to do a good job in daily cleaning and maintenance of the friend's mouth and replace the fuel filter. I hope to carry out the above analysis.
