Renault Scenery Idle Jitter Troubleshooting

Described may be like the state of the engine cylinder shortage, please check to replace the ignition wire or ignition coil.

Renault Scenery Idle Jitter Troubleshooting Maybe you are local ethanol and then Ethanol fuel emits a lot of moisture after combustion, corroding the exhaust pipe. Ethanol fuel begins to deteriorate in 7 days, it is recommended not to add a very full amount at a time, if the number of kilometers run is less, you can use the company * general fuel cleaner on a regular basis to have a good cleaning effect on the moisture of the ethanol in the oil circuit, so that the pipe is not easy to rust.

Analysis of the causes of car shake:

1. Suspension system problems.

Body shake is also related to the aging of the suspension system. It is mainly responsible for filtering out the shake of the engine when it is running, and if there is a problem with the suspension, these vibrations will be transmitted directly to the steering wheel and cab, affecting the driving. When the engine is idling, it is easy to cause shaking when the electrical system in the car is turned on.

The engine will increase the load when the electrical appliances are turned on, causing the idle speed to drop, and to compensate for the jitter caused by the idle slip, the engine will automatically increase the speed by partially. Therefore, when the electrical system is turned on, especially when the orange is rotten, the engine will often shake. This jitter is likely to be caused by the aging of the shock absorber and needs to be replaced in time.

2. Tire problems.

For tires, the tire must be balanced once when the car is replaced with new tires and new steel rims, otherwise the steering wheel will be prone to shake when the counterweight is uneven. If you find that the tire weight is not equal, you need to add lead to the inside of the rim to average the weight of the tires on both sides. Whether it is a general steel ring or a lightweight aluminum ring, it may deform or crack when subjected to a certain external force.

Deformation of the rim can cause shaking when driving, uneven weight of the rim can also cause shaking when driving, and incorrect angle of the rim can also cause shaking when driving.

3. Throttle problems.

The most common cause of car shake may be a dirty throttle valve and excessive carbon build-up in the fuel injector. After the car travels for a period of kilometers, the throttle valve will be too dirty and the throttle will not close tightly or the idle motor will be stuck, resulting in the engine idle speed is too high, and the carbon deposits generated by the engine in the process will also cause the vehicle to shake, especially when starting the car, the engine will shake more than normal, and even sometimes there will be a phenomenon that can not be started at one time. Therefore, when the body shakes, the first thing to do is to check the throttle and fuel injectors.

If you find that the throttle valve is too dirty or the fuel injector has too much carbon deposit, you should clean it with fuel injector cleaner or Yuanwei throttle cleaner in time.

4. The oil pressure is unstable.

If you still find that the body shakes after these are finished, it is recommended that you go to the repair shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is not normal, the intake pressure sensor is wrong and improper work will cause the body to shake.

Clean the throttle and idle motor.
