Fox turned on the air conditioner. What's wrong with unstable idle speed?

Fox turned on the air conditioner, and the reasons for the unstable idle speed are: oil storage in the throttle and carbon deposition in the throttle.

The solution is: if there is engine oil and carbon deposit in the throttle of the car, you need to go to the car's 4S shop or repair shop to clean the throttle of the car in time, which can solve the problem of unstable idle speed when Fox turns on the air conditioner.

Blocked air intake will cause idling, and there is carbon deposit or engine oil in the throttle, which is the most common cause of unstable idling. Due to carbon deposition, the throttle will affect the opening and air intake, which will make the engine speed fluctuate after the car is started, which is very unstable and accompanied by strong jitter.

Extended data:

The introduction of the unstable idle speed of the car is as follows:

The throttle valve has serious oil storage or carbon deposition, including unclean air intake, which makes it difficult to start the car in cold weather. When the throttle is dirty, it needs to be cleaned, and the throttle cleaning itself is also a routine maintenance item.

Spark plugs will also deposit carbon, which can be cleaned to restore the activity of spark plugs, but some spark plugs will have poor performance when their service life is approaching. The spark plugs on individual cylinders are weak, which will affect the performance of the car. Under normal circumstances, the failure of spark plug will cause the car to have "fire" symptoms.
