Hi there. It is quite possible that your car has entered what we call a fail safe or "limp mode" due to an error code being activated and stored in the ECU. This will occur when the ECU or a sensor detects a mechanical or electrical fault on one or several fuel, ignition, cooling or powertrain systems. It’s designed to allow you to safely "limp" your car to a repair facility or home so a professional mobile mechanic can complete a car is slow to accelerate inspection and determine the right course of action. It is also possible that this issue is caused by a loose vacuum line or other component like the throttle position sensor.
