Check the turbo's By Pass Valve-(BPY) for correct operation. If this is faulty and is stuck open, the boost pressure created wil cause to intake pressure to recirculate back into the the flow. Also check the usual spark/ignition components for operation. Look on the intake rail and find the grounding wires from the system and remove them, clean, and reinstall them as these will cause similar problems. Two years isn't that long between tune-ups, so check for loose hoses and vacuum tubing. Keep us posted!
