Hi there,I would suggest you give the engine an "upper cylinder clean" with a product like Subaru Upper Engine Cleaner or equivalent.All engines suffer from carbon buildup, some are more prone to intermittent misfire from valves not sealing well, to the carbon acting as a sponge when the injectors fire.I have fixed many cars with this product, makes them like new.Hope this helps.Gary

Hi again,Your local auto parts store would have a product called "Sea Foam".It will do tha same job as the Subaru product.I hope my advice has been of assistance to you.Please rate my service at your nearest convenience.Kind regards Gary
