Mazda cx5 Engine Jitter (What is the reason for the loud engine noise after Mazda cx4 starts)

It is normal that Mazda cx4 engine will shake slightly when the hood is opened. This kind of shaking is a stable and regular shaking, which is a normal phenomenon. If the jitter is serious, the throttle valve needs to be repaired and checked.

Common causes of automobile engine jitter;

1, the machine foot glue is aging or loose.

Foot glue is a rubber block between the engine and the frame. Its function is to reduce the vibration and buffer when the engine works and fix the engine. Once these machine feet are aged or loose, the engine jitter will be extremely obvious.

The engine cylinder is missing.

Engine cylinder shortage mainly refers to the abnormal operation of one or more cylinders of the engine, which is manifested by the obvious intermittent exhaust gas flow from the automobile and the violent shaking of the exhaust pipe, which can obviously feel the engine shaking, sometimes accompanied by abnormal sound, and is mostly related to the failure of the ignition coil.

3. Carbon deposition

The carbon deposit here includes cylinder carbon deposit, throttle carbon deposit, spark plug carbon deposit, intake carbon deposit and so on. These positions are closely related to the power output of the engine. When there is too much carbon in the engine, the ignition energy of the automobile will be reduced, and the intake efficiency will also be reduced, which will eventually lead to the symptoms of engine jitter and weak acceleration.

4. Cold start

When the car is cold started, the engine lubrication effect is poor, the oil fluidity is poor, the viscosity is high, and there will be abnormal noise of mechanical wear. Cold start, low coolant temperature, rich mixture and insufficient combustion will all lead to engine jitter, which is generally normal and will get better after hot start.
