Wait - are there reports of carbon buildup on these engines? Lots of noise, little data.
Its a new direct injection motor... the amount of people experiencing carbon buildup so far is tiny and the amount of people that are active on a forum to share about this issue is even tinier. All the symptoms point at carbon buildup and the intake related code basically seals the deal for me...
Its a first generation, and mazdas first attempt at making a mainstream motor with direct injection (other then the 2.3L MZR from the past) so ignition/fuel timing is obviously not perfect yet.
Then again, people who regularly rev out the engine dont seem to have any problem with this even at high mileage, so I think it isnt much of a problem unless you dont rev the car hard ever.
