When I drive and start to de-accelerate, its like my gas pedal total cuts out, RPM don't drop and the car don't quit. It just cuts out, I feel this at highway speeds, its like the accelerate totally cuts out when slowly letting off the gas pedal. I can press the gas again and it comes back. I just had my car checked out and nothing came back as wrong and no lights are on...anyone have any clue to this, this is driving me NUTS!
