When you notice the gas, how badly is it running? Does it sound like you have a few dead cylenders? Is the smoke actually oil burning or does it run extreamly rich? If it's rich, I would first check the fuel pressure regulator. If it's oil, take a look at the intake gasket. Also, take it to a nationally recognized parts store and have them scan the computer for codes. See if anything has been stored in the computer.

Let me know what you find.
