Have the PCV system checked to see if it is plugged up and have it scanned for codes. To check the PCV you need a manogram vacuum gage you insert to the oil dipstick tube and check for vacuum. Min specification is -0.2kpa or lower. If it is higher then that then the PCV system is plugged up. Also if you have turbo it is recommeded you use premium fuel.
