I believe that many car owners will feel that the new car they bought is not as smooth as before, and they will also find the problem of jitter. “Body jitter” is a signal that the car tells you that there is a problem, then What is the solution? The following editor will help you analyze it one by one.
1. Serious engine carbon deposition
The most common cause of car jitter is that the throttle valve is too dirty or There is too much carbon deposition in the fuel injector, because the gasoline adsorbed on the carbon deposition is sucked into the cylinder by the engine to burn after starting the vehicle. Solution: Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned.
2. Ignition system problems
One of the reasons for jitter is that the spark plugs, high-voltage wires and ignition coils are not working properly. Solution: Check whether the spark plug is too much carbon and replace the spark plug.
3. The oil pressure is unstable
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, which will cause the body to shake. Solution: Check oil pressure and replace parts if necessary.
4. Aging of engine parts
Car vibration is also related to the aging of engine parts. At this time, if there is a problem with engine parts, these vibrations will be transmitted to the steering wheel , in the cab, causing jitter when idling. Solution: Replace auto parts.
