What Causes Jerking Sensation While Driving?

[OJosiah]

There are several reasons for a jerking sensation while driving, including a clogged air filter, damaged solenoid valve, and sludge buildup in the transmission fluid blocking the valve body's oil passages. Clogged Air Filter: If the air filter is not cleaned for a long time, it can allow a large amount of dust to enter the combustion chamber. The dust can then mix with atomized fuel and adhere to various components, such as the idle speed control valve's small holes and the throttle plate. The solution is to clean the air filter. Damaged Solenoid Valve: This is a major cause of jerking. Jerking can be either sporadic or occur at fixed intervals. Sporadic jerking happens unpredictably, while fixed jerking occurs at specific RPMs, during certain gear shifts (e.g., shifting from 2nd to 3rd gear), or at fixed speeds. The solution is to repair or replace the solenoid valve. Sludge Buildup in Transmission Fluid Blocking Oil Passages: Sludge in the transmission fluid blocking the valve body's oil passages can cause jerking. Over time, this can lead to a series of transmission issues, such as overheating, harsh shifting, and slipping. The solution is to clean the sludge from the transmission.
