Nothing is more frustrating than a problem that won't go away, simply because you don't know how to fix it. This can be anything from a simple motor hesitation, to a misfiring of the engine at 4000 RPM. Strange symptoms can come from nowhere, and they can linger forever if you don't know the right person to diagnose the problem. If you even have a situation like this with a Subaru motor, CALL JOHN at Outback. He's seen almost everything there is to see and likely has the information you need to fix your problem. If he can't help you over the phone you can bring your car in to have it diagnosed by a pro.
