On friday my 2004 WRX suddenly began chattering as I reached 3000 rpm or so. My first thought was a loose heat shield on he catalytic converter or elsewhere in the exhaust system. Decelerating in gear, the noise got louder, almost as if an exhaust leak or turbo blow-off valve. Noise now appears at lower speeds, power is down, and car is difficult to start, with engine cranking very slowly. I'm limiting driving to essential travel, and have a dealer appointment tuesday (car still under warranty). Gets regular maintenance, required octane, and never abused, but driven to the car's capabilities, otherwise I wouldn't have a WRX. Any ideas? Burnt valve? Turbo issue (first occured to me hat noise became evident just as turbo was kicking in). Exhaust leak or is that too simple? Appreciate any input before throwing myself on the mercy of the dealer service dept, although they've done alright by my wife's car.
