Cold car starting engine is missing cylinder and shaking, fault code P231000

September 4, 2024

Fault symptoms: The car is now used almost on weekends. Later, it was discovered that after a few days of parking, the car started cold, the engine was shaking and loud, and it felt like the cylinder was missing. After starting the second/third time, the engine light came on, and after starting the third or fourth time, it returned to normal. The engine vibration disappeared, driving normally, there would be no problem with igniting the hot car behind, and the engine light disappeared. If you drive it every day, you will almost never encounter this problem. At first, I suspected it was carbon deposition and was ready to deal with it.
Fault code: P231000. When I encountered this problem one day, I took advantage of the engine light to read the fault code and recorded P231000.
Store solution: Said it was to repair the computer board, but the quotation was always cheap, which was enough for me to replace it with a second-hand computer board. Online inquiries also point to the computer board.

Which forum god has encountered this failure?

Finally, I went to a place in Xinchutian’s family that specialized in repairing computer boards and replaced 4 capacitors, which cost 400 yuan.

Look carefully, the capacitor is leaking liquid

All four small capacitors were removed, and the store owner said they would not break.

I replaced 4 capacitors made in Chengxing, Dongguan. The boss said that they would not be damaged even if they were scrapped in the car.

Still very professional
It’s all computer boards

I took a photo casually, many stores
