There are many probable causes. You could have a bad (or broken) piston ring which would allow raw fuel to exit the affected cylinders during the compression stroke. You could also have a faulty EGR or PCV valve. You'll have to take the vehicle into a friendly local dealer so they can "scope" the engine.
