What if Nissan Sylphy turns on the air conditioner at idle speed?

The solution is: check whether the spark plug has too much carbon, and if so, replace the spark plug. If the carbon deposit in the engine has been cleaned, the throttle valve has been cleaned, the fuel pad and spark plug have been replaced, and the car body is shaking at idle speed, it is recommended to go to the 4S shop to check whether the fuel supply pressure and intake pressure sensors are normal, because the abnormal fuel supply pressure of the oil pump or the incorrect value of the intake pressure sensor and poor operation will lead to the car body shaking. With the increase of vehicle mileage, carbon deposits will be produced in many places, including the accelerator. If the throttle valve is dirty, it will block the air intake, resulting in insufficient or reluctant engine-driven compressor. Therefore, the above problems have arisen. The problem caused by dirty throttle can be solved by cleaning and matching throttle.
