1) Check all the vacuum hoses for a leak in the rubber hose or a hose that isn't connected. Vacuum leaks cause motors to shake and stumble on acceleration.
2) There's a plastic T connection on the back side of the engine behind and under the air cleaner box. That T connector joins together three air hoses of different sizes and is prone to breaking from heat stress. Only a Subaru dealer will have this part.
3) Even though the spark plug wires are new, you may have a bad one. Don't waste your money on cheap parts; they cost more in the long run.
Good luck!

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

There could be many issues. These codes read your engine is running too lean. Check : all your vacuum hoses for leaks, PCV valve and hose, MAF sensor. This may require an experienced technician to figure this out. Hopefully I help'd!!
