How do I fix unwanted acceleration

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Regal. Unintended acceleration can be dangerous, so it's essential to address it quickly. A common cause is a sticking throttle plate due to buildup in the throttle body. Inspect the throttle body for carbon buildup and clean it thoroughly with throttle body cleaner. Another possibility could be a faulty idle air control valve or a malfunction in the accelerator pedal assembly. If the problem persists after cleaning and inspecting these components, it may be due to a more complex issue, like a problem with the engine control module or sensors. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
