Shaking car were indicative of what

Shaking car were indicative of what Car use for some time, some owners may find some little body shake, but do not know what went wrong. "Body shake" is a signal that tells the owner the car has a problem. Professional teacher told us more than soldiers, the body shake may seem a trivial, if not pay attention to testing, will lead to a large hidden faults. So, the body shake is a problem caused it? Ordinary car owners how to determine and resolve?
Shake that body in motion
If the driving process, the body found in a slight jitter or offset, is generally caused by tire failure. First, the tire balance may be in poor condition, require the owner as soon as possible to do a wheel alignment and balancing, if the vehicle does not tire balancing to do some wandering.
Outside a situation is more serious, probably because the deformation caused by steel ring, which requires the owner to a professional repair shop check. This situation generally occurs in the vehicle body a longer life. General automotive replacement tires, new rims tires when they do a balance, otherwise the weight on the steering wheel is not likely to occur when the average jitter phenomenon. Body shake on driving comfort and control to determine the effect will be.
The third situation is unbalanced because the shaft deformation caused by the general situation in the chassis of the car had more impact.
Body shake when idle
Jitter is a lot of idle vehicle owners often face the situation. If the owners start the vehicle or the vehicle is not suspended off the engine, if found to significantly shake the body, it may mean that the vehicle the following three conditions exist:
1 Engine serious coke
Jitter caused by car is the most common cause of injector throttle too dirty or too much coke. When too much carbon deposits inside the engine when cold start injector head may be emitted carbon absorbs gasoline, resulting in cold start mixture too thin, making difficult to start, this situation, only the carbon absorbed by the gas until saturation, it is easy with the car, the car adsorbed on carbon will be on gasoline engine combustion cylinder vacuum suction aspiration, and the mixture thickens, when the engine's fuel mixture when the concentration of rare, resulting in cold start idle jitter. Lower the temperature, cold start the greater the amount of oil needed, the presence of carbon will affect the cold start of the more successful or not.
The solution: Clean oil, check the idle speed motor should be cleaned if there is carbon.
(2) ignition system problems
Check spark plugs, ignition coil high voltage wire and working conditions, the ignition system working poor, bad spark plug arcing condition can cause the same type of symptoms.
Solution: Check the spark plug is too much carbon, the replacement of spark plugs.
3. Hydraulic instability
If you have already cleaned up the engine carbon deposits, washed throttle, oil pads, and spark plugs replaced, are still found in the body shake when idle, we recommend that you check the fuel supply to the 4S shop inlet pressure and pressure sensors are normal, if the oil pump pressure is not normal or intake air pressure sensor values ??will cause errors and bad body work jitter.
Solution: Check the oil, if necessary, replacement parts.
4, engine components aging
Automotive engine feet with jitter (also known as machine paw pads) aging. Engine Mount is the engine suspension system, engine feet when the engine is running is responsible for absorbing the subtle jitter, if the engine foot problems, these vibrations will spread to the steering wheel, the cab, resulting in jitter when idle.
The solution: replacement parts
