I have a 2004 Ford Focus that has 18,000 miles. I have already had to have the throttle replaced twice; after several thousand miles, the throttle begins to stick and it becomes more difficult to apply light pressure to the gas peddle. The throttle will stick and as I apply pressure to the gas, the car will surge forward when the force finally overcomes the throttle sticking. This causes problems in commute stop/go traffic as I have several times almost hit the car in front of me because of the surge.
