What Causes the Jerking During Sudden Acceleration in Camry?
2 Answers
Camry's jerking during sudden acceleration is caused by clogged fuel lines, excessive carbon deposits, poor fuel quality, and spark plug failures. Below are the specific reasons for jerking during sudden acceleration: Excessive carbon deposits on throttle body, fuel injectors, and intake manifold: Many malfunctions are caused by carbon deposits, and some vehicles experience jerking due to carbon buildup. It is recommended to regularly clean carbon deposits to resolve the jerking issue. Poor fuel quality: Substandard fuel quality leads to incomplete combustion. Replacing the fuel can solve the problem. Abnormal ignition: If the ignition is not functioning properly, it is necessary to have it inspected and repaired at a service center to avoid further safety hazards.
My eighth-gen Camry had the same issue - it would jerk noticeably when I stomped on the accelerator. From experience, the most common culprit is overdue transmission fluid changes, especially for vehicles over 100,000 km. Toyota's 6AT transmission is actually quite durable, but degraded fluid causes sluggish valve body response, making gear shifts feel like grinding cogs. If spark plugs haven't been changed in over 60,000 km, hard acceleration can make the car buck like riding a horse. Also, a dirty mass airflow sensor disrupts the air-fuel mixture - when the ECU miscalculates fuel delivery, hesitation occurs. Last time my car had this symptom, changing the transmission fluid restored buttery-smooth operation immediately.
