KIA k5 Idle 600 Body Trembling

There are many factors that affect the body jitter of KIA k5 idle 600. Mechanical failure of air intake system, fuel system, ignition system and engine will lead to unstable idle speed of engine. Body jitter includes: serious carbon deposition in the engine, failure of ignition system, unstable oil pressure and aging of engine parts.

Reasons for idling jitter:

1, engine carbon deposit is serious.

The most common cause of automobile jitter is that the throttle valve is too dirty or the fuel injector has too much carbon deposit. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by a large amount of carbon deposit during cold start, which makes the cold start mixture too thin and difficult to start. In this case, it is easy to start the car only if the gasoline with carbon deposits is saturated. After the car starts, the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the vacuum suction of the engine for combustion, which will make the mixture thicker and the combustible mixture of the engine thinner and thicker, leading to cold start.

2. There is something wrong with the ignition system

Check the working conditions of spark plugs, high-voltage lines and ignition coils. If the ignition system is not good and the spark plug does not jump, it will also lead to such a failure.

3. The oil pressure is unstable

If the engine carbon deposit has been cleaned, the throttle valve has been cleaned, and the oil pad and spark plug have been replaced. And the body will shake when idling. It is recommended to go to 4S shop to check whether the fuel supply pressure and intake pressure sensors are normal. If the oil supply pressure of the oil pump is abnormal, or the value of the intake pressure sensor is wrong and the work is not good, the body will shake.
