What Causes the Geely Emgrand to Jerk at Startup and Lack Acceleration?

[VonJesse]

Reasons for the Geely Emgrand jerking at startup and lacking acceleration: 1. Air intake pipe leakage leading to an overly lean air-fuel mixture; 2. Low fuel pressure, clogged fuel injectors or fuel filter causing insufficient fuel injection or delayed fuel increase; 3. Abnormal signals from sensors such as the air flow meter, intake manifold absolute pressure sensor, and throttle position sensor, resulting in no or insufficient increase in fuel injection; 4. Abnormal sensor signals causing incorrect ignition timing, leading to delayed ignition. The Geely Emgrand is a sub-brand under the Geely parent brand. The Emgrand GL is a compact car under the Geely Emgrand lineup, with dimensions of 4725 mm in length, 1802 mm in width, and 1478 mm in height, and a wheelbase of 2700 mm. In terms of suspension, the Emgrand GL features a MacPherson independent front suspension with a stabilizer bar and a torsion beam rear suspension.
