What Causes the Geely Emgrand to Experience Weak Acceleration and Shaking?

[GarrettLynn]

Specific reasons for the Geely Emgrand experiencing weak acceleration and shaking are as follows: 1. Vehicle engine malfunction: When the engine is running, pressing the accelerator pedal does not immediately increase the engine speed, resulting in sluggish acceleration response. During acceleration, the engine may shake or exhibit fluctuating speeds, sometimes accompanied by backfiring or popping sounds. 2. Weak acceleration in the Geely Emgrand may be due to a dirty throttle body or excessive carbon buildup in the fuel injectors: Clean the fuel system promptly and check if the idle speed motor has carbon deposits that need cleaning. 3. Specific causes of engine weak acceleration issues: Intake manifold leaks leading to overly lean air-fuel mixture, low fuel pressure, abnormal signals from the intake manifold absolute pressure sensor and throttle position sensor, weak spark due to faulty spark plugs or high-voltage wires, and malfunctioning exhaust gas recirculation system.
