Id be getting a compression test if the plugs oily.Its common on all red busas.
If the plugs just black and wet i,d check the injectors and spark.No4 injector always seems dirty as its the last on the line.Fault codes c32-35 are injectors.Just eliminate one thing at a time.Oil in the airbox would likely come from the pcv hose.When you start it have this hose pulled off the airbox and put your thumb over it and feel for pressure when you rev it(their should be bugger all unless the rings are allowing blowby).
