The fault prompt of Lang Lang 2000 rpm jitter.

Does the subject want to ask "the reason for the jitter fault prompt of Langlang 2000 rpm"? Ignition system problem, fuel system problem, air supply problem, engine sensor problem, ignition sequence problem.

1. Ignition system problem: the ignition coil, spark plug or ignition circuit is out of order, resulting in jitter. Check the status of the ignition system, ensure that the spark plug and ignition coil work normally, and check whether the connection circuit is good.

2. Fuel system problem: insufficient oil supply or blocked fuel nozzle leads to jitter. You can check whether the fuel filter needs to be replaced, and troubleshoot the fuel pump or nozzle.

3. Air supply problem: air filter is blocked or air inlet pipe leaks, which leads to unstable air-fuel ratio and jitter. Check the cleanliness of the air filter and whether the air inlet pipeline leaks.

4. Engine sensor problem: Some engine sensors, such as air flow meter and throttle position sensor, may lead to unstable engine operation if they fail or fail.

5. Ignition sequence problem: If the engine ignition sequence is incorrect, it will also lead to jitter. Check the ignition sequence of the engine to ensure that all spark plug coils are installed and connected correctly.
