How to Solve the Jerking Issue When Decelerating and Accelerating in Nissan Sylphy?
2 Answers
Excessive carbon deposits in the throttle body, fuel injectors, and intake manifold can cause jerking sensations. The solution is to clean the carbon deposits. Poor fuel quality leading to incomplete combustion can also result in jerking. It is necessary to switch to higher-quality fuel. Faulty spark plugs or ignition coils can cause jerking as well. Replace the spark plugs and ignition coils.
I had the same issue with my Sylphy. The car would jerk when letting off or stepping on the gas, especially noticeable during low-speed following. I checked myself and found the transmission fluid was a bit dirty—replacing it improved things significantly. However, there was still slight jerking afterward, so I took it to a repair shop. The mechanic said the throttle body had severe carbon buildup. After cleaning and an ECU reset, the fault code disappeared, and the car drove much smoother. I recommend checking the transmission fluid level and condition first—CVT models rely heavily on fluid, so change it every 50,000 km. Avoid sudden acceleration in daily driving, and easing off the gas before red lights can reduce jerking. This is a common issue with the Sylphy, and early action can prevent major repairs. My 2017 model hasn’t had a recurrence in three years—just sharing to save you some trouble.
