Today, I was driving my wife s 2004 Honda Civic in the highway at about 60 miles per hr when all of the sudden the car started accelerating as if it was in cruise control. . I took my foot off the gas pedal and pressed the brake with little results. The brakes felt so hard as if they were locked. Then I decided to change gears to d2 and together with the emergency brake I was able to slow down the car a bit. After that, I pulled over the brake down lane at about 10 miles per hour but I still could not stop the car. With the help of the emergency brake I was able to stop the car however, the engine was still running as if it was accelerating. This is when I decided to put it on neutral and follow by a loud noise the engine finally stop running. . . . Thank god no one was hurt. . . .
