thanks guys! but i have changed the spark plugs that has all been done, i will check the idle air control valve that could be the problem, and i will also look into replacing the fuel filter, and look to change and check the fluids. i have never owned a high performance car with a turbo before, so i just didnt know if there was anything different with the basic tune up? But makes sense. and yes i do have a record of all the maintenance done to the car i am pretty anal on keeping things up to date.
also my engine makes a ticking noise at idle, i have done a lot of research on it and they say its pretty normal for subarus? do any of you guys have this same ticking or experience? its there at idle, but goes away at about 3,000 rpms? it seems to be coming from the drivers side up where the timing belt cover is in the bay with the cam shafts? but not entirely sure? could be higher and deeper in the engine? but the car drives fine and shifts smooth!
