I noticed that the car did not decelerate when I removed my foot from the gas pedal. When I braked, the engine continued to race. I put the car in neutral and I could hear the engine race even faster. At the light I kept it in neutral and gave it gas while braked. Then it went back to normal idle speed. It has done this several times since that first incident. Previous to that first incident, I noticed that the cruise control no longer worked.
