What Causes Unstable Idle and Jerking Sensation in Mazda6?

[VanKinsley]

Here are the specific reasons for unstable idle and jerking sensation in Mazda6: 1. Engine oil passage blockage: The combustion of fuel is determined jointly by engine ignition, intake, and fuel injectors, which are the power source of the engine. If the intake volume decreases, ignition weakens, or the fuel injection reduces, the power will be insufficient, leading to a jerking sensation. 2. Dirty transmission fluid: This can cause damage to the solenoid valve. If sludge in the transmission fluid circulates and blocks the oil passages in the valve body, jerking issues will occur. Over time, this can lead to a series of transmission problems such as overheating, impact, and slipping. 3. Break-in period: Slight jerking sensation during car driving is normal because the power output of the vehicle and the meshing of components are not at their best levels. Additionally, the transmission computer has a self-learning mechanism that requires continuous adjustment of oil pressure for gear shifting.
