Hello everyone, I am trying to deal with a complicated problem. Therefore, I will try to explain every detail to you. Sometimes when my car is idling, cylinder number 3 stops working and the radiator fan runs at full speed. After waiting 5 minutes, the radiator fan stops and the car continues to run smoothly again. There is no problem in its performance. It usually doesn't do this while driving, there is a momentary vibration when idling. The fault light starts flashing and the engine operates as 2 cylinders. Sometimes I unplug the battery cable and plug it back in and continue driving the car all day long. Oxygen sensor and crank sensor changed, timing set changed approximately 50,000 kilometers ago. I don't want to replace a solid part anymore. There is an interesting situation that caught my eye. If I turn on the air conditioner, I do not encounter this error all day long, that is, I do not encounter this error when the idle speed is above a certain level. I suspect that the timing of the cam belt is slipping or that there is a problem with the valves. These are of course problems that I guessed without any examination. Unfortunately, it is not possible to focus on a single area to find this complicated error, there are hundreds of parts in the engine and it could be from any of them. error codes p1339,p0053. sometimes p0014,p0420 View attachment 116742
