What is the reason for the idling 1200 rpm jitter of Deutz engine?

1, the throttle valve is too dirty, resulting in insufficient intake of the engine when waiting for the bus, resulting in jitter.

2. The electronic throttle is damaged. Under normal circumstances, the exhaust flow emitted by automobiles is obviously intermittent, and you can obviously feel the trembling vibration of the engine, sometimes accompanied by sudden sounds.

3. There is slight air leakage in the intake branch pipe. After this happens, it is recommended to go to the repair shop to clean the throttle and match the throttle.
