    ANY DTC"S/??.OR CHECK ENGINE LIGHT ?? WOULD HELP.IN THE DIOGNOSIS.BUT FOR THE AIR WHOOSHING SOUND, I WOULD START BY CHECKING FOR ANY TORN TURBO INTERCOOLER RUBBER HOSES.ONE IS LOCATED JUST OBOVE THE RADIATOR,ONE AT TURBO ISTSELF.AND ONE LONG HOSE ON THE LEFT SIDE OF THE AIR FILTER BOX ,COULD BE A COIL,OR A BAD SPARK PLUG, FOR IT FEELING LIKE ITS NOT RUNNING ON ALL FOUR CYLINDERS.
