I have a subaru legacy 2005 2.0 non turbo from japan when I start the car in the morning I get a misfire and it hesitates when I step on the gas peddle I have changed the plugs and wires and clean the injectors and still getting the problem
Engine running rough or misfiring can be cause by the following: 1. Defective spark plug.
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. Vacuum leak
5. Fautly fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.

I would check with the subaru dealer I think that year they have had a update for that problem. It would be a computer download for your engine computer you just have to tell them your vin over the phone and they can check.
