What Causes the Lack of Power and Jerking During Startup in the Cruze?

Here are the specific reasons for the lack of power and jerking during startup in the Cruze: 1. Clogged engine oil passages: The combustion of fuel, which is the power source of the engine, is determined by the ignition, air intake, and fuel injectors. If the air intake decreases, the ignition weakens, or the fuel injection reduces, the power output will be insufficient, leading to a jerking sensation. 2. Dirty transmission fluid: This can cause damage to the solenoid valves. If sludge accumulates in the transmission fluid and circulates within the transmission, blocking the oil passages in the valve body, jerking issues may arise. Over time, this can lead to a series of transmission problems such as overheating, harsh shifting, and slipping. 3. Break-in period: Mild jerking during driving is normal during the break-in period because the vehicle's power output and component engagement are not at their optimal levels. Additionally, the transmission control module has a self-learning mechanism that continuously adjusts oil pressure for smoother gear shifts.
