Hi there. There could be an issue with the throttle position sensor (TPS) or a sticky throttle plate. First check to see if the throttle plate is sticking. If the plate is working properly, then check the TPS for any damage and look at the plug for any burns or moisture. Check the computer for any pending codes. If the vehicle jerked, even if the engine light is not on, there could be pending codes. If you need further assistance with the vehicle jerking as if another car hit your vehicle, then seek out a professional, such as one from Your Mechanic, to help you.
