Yes, a faulty O2 sensor can indeed cause a car to jerk. The oxygen sensor plays a critical role in your vehicle’s engine management system, helping to regulate the air-fuel mixture. If the O2 sensor is malfunctioning, it can send incorrect data to the car's computer, resulting in an imbalanced air-fuel mixture. This imbalance can cause the engine to run lean or rich, leading to irregular engine combustion and, consequently, jerking or hesitating during acceleration. Getting the O2 sensor checked and replaced if necessary can resolve this issue.
