When coming to a stop or rolling in idle I have a pulsating vibration in my brake and gas pedal. Example, in a parking lot driving slow i can feel the vibration in my gas or brake pedal. Its not a fast pulse but fairly slow. I guess it feels like a heart beat type. Another time it happens is when I drive a long period and when i come to a stop I can feel the vib in my brake pedal. It seem worst when I drove it a long time(50+miles). It happens mostly at low speeds(below 25mph). Thanks.
