Hippocampus familia idling too fast!

It may be caused by the failure of water temperature sensor or throttle body. There is also the problem of collecting oil and clamping the car. At present, EFI vehicles all use the engine to control computer fuel injection. When the engine is in neutral at high speed, it will automatically cut off the fuel injection and only keep idle. When taxiing in neutral, the computer control unit forcibly closes the throttle to a small angle. Because the throttle is dirty and the air intake is not smooth, the car will pinch. In addition to engine oil and throttle, when the engine is braked, the engine and body fixing bracket are too soft or the gap between gearbox differential is too large, which may lead to oil accumulation and trucks. It is recommended that you regularly clean the throttle valve, fuel injector and air intake when the vehicle is driving for 20 ~ 30 thousand kilometers, even if there is no fault, and check the carbon deposition in the combustion chamber and spark plug. Also check all the above.
