What Causes Sudden Car Shaking?

[MacDonovan]

Engine shaking can be caused by damaged engine mounts, cylinder misfires, carbon buildup in the combustion chamber, throttle body carbon deposits, etc. Below is an introduction to throttle-related content: Function: The throttle's function is to control air intake into the engine. After entering the intake manifold, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. Principle: The working principle of the throttle involves traditional engine throttle control mechanisms that operate via cables (flexible steel wires) or rods, connecting the accelerator pedal to the throttle linkage plate. Electronic throttles primarily use throttle position sensors to adjust the throttle opening angle based on engine power requirements, thereby regulating the air intake volume.
