What are the reasons for the weak acceleration of Jianghuai Junling?

[EmilianoMarie]

The reason for the weak acceleration of Jianghuai Junling is due to excessive carbon deposits on the throttle valve, etc. The following are the specific reasons for the weak acceleration of Jianghuai Junling: 1. Carbon deposits inside the engine: When there are too many carbon deposits inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in a too lean mixture during cold start, making it difficult to start. 2. Ignition system: Problems with the ignition system. Check the working condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or bad spark plug firing can also cause such fault phenomena. Check if the spark plugs have excessive carbon deposits and replace them if necessary. 3. Unstable oil pressure: Abnormal fuel supply pressure from the fuel pump or incorrect values and poor performance of the intake pressure sensor can cause body shaking. Check the oil pressure and replace the components if necessary.
