This is due to a air to fuel ratio imbalance, either the fuel system is delivering too much fuel into the engine or there is not enough clean air (oxygen ) a few things to look for:
•Faulty injectors (injectors need attention at about 100.000 to 120 000 miles)
•Faulty injector pump
•Dirty air cleaner
•Turbocharger or intercooler faulty
•Problems within cylinder head, valves clogged up due to faulty EGR (exhaust gas recycling unit)
