What is the reason for the body shake at idle?
The most common cause of car jitter is that the throttle is too dirty or the fuel is too much. When the engine inside the coke too much, the cold start fuel injection of gasoline will be a lot of coke absorption, resulting in cold start of the mixture is too thin, making the start difficult, this situation, only to wait until the carbon deposition of gasoline Saturated, easy to car, the car after the adsorption of carbon in the charcoal will be the engine's vacuum suction suction cylinder combustion, but also make the mixture thicker, the engine combustible mixture when the dilute, resulting in cold start Idle jitter.
Car jitter is also related to engine foot aging. The engine foot is actually the engine shock absorber system, the engine is responsible for absorbing the engine when running the slight jitter, if the engine feet problems, these vibrations will be transmitted to the steering wheel, the cab, causing idle when the jitter.
If you have cleaned up the engine coke, wash the throttle, replaced the oil pad and spark plugs, etc., still found the idle body when the body jitter, it is recommended that you go to the 4S shop to check the fuel supply pressure and intake pressure sensor is normal, if the oil pump Pressure is not normal or intake pressure sensor values are wrong and poor work will lead to body shake. The solution is to check the oil pressure and replace the parts if necessary.
Check the spark plug, high voltage wire and ignition coil working conditions, the ignition system is working poorly, spark plugs flashing the same situation will lead to such failure. The solution is to check whether the spark plug is overcame and replace the spark plug.
