Default Misfire on cylinder 1 & 3

Code: P0301 P0303
Year/Make/Model: 2006 Subaru WRX STI
Mileage: 60300
Fix for problem: I bought the car from the Oak Lawn Mazda dealer with 50k It is completely stock. I replaced the spark plugs with good plugs and I also flipped my coils and the misfire is still on the same two cylinders. I also looked into the Carfax and the turbo was replaced by a subaru dealer and also the intercooler also looks like it was replaced. The check engine light comes on and goes off sometimes and it i can only feel the misfire when I'm at a stop.... Any idea what it can possibly be? Any help would be greatly appreciated.
