Sounds like the car isnt getting warmed up. 2 miles is not a lot of time and the computer is probably commanding high fuel to get the engine up to heat range. You may check your air filter or also trying running some top clean through the engine. Low driving time could build up a bunch of carbon in the cylinders.
