15 Camry double spray 2. What is the reason for the seat jitter when waiting for the red light?

1, the most common reason for car jitter is that the throttle is too dirty or the fuel injector has too much carbon deposit. If the engine has too much carbon, the gasoline sprayed by the cold start injection head will absorb a lot of carbon.

2. Car jitter is also related to the aging of engine feet. The engine foot is actually the damping system of the engine. The engine foot is responsible for absorbing slight vibration when the engine is running. If there is something wrong with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing idling jitter.

3. Check the working conditions of spark plugs, high-voltage lines and ignition coils. Poor ignition system and poor spark plug misfire can also lead to this fault.

4. Engine cylinder shortage mainly refers to the abnormal operation of one or more cylinders of the engine, which is manifested as: the exhaust gas flow discharged by the automobile is obviously intermittent, and the exhaust pipe is seriously shaken, and the engine jitter can be obviously felt, sometimes accompanied by sudden noise.
