My money is on the fuel pump.....if it isnt getting the correct fuel pressure the engine will show these symptoms.

its a cheap fix (~$180) and also a necessary upgrade to the car if you are going to be pushing more power from the engine.


I would also suggest using a can of upper engine cleaner, its ~$15 from subaru and be enough for 2 goes.
