Try cleaning your O2 sensor. Remove it from the driver's side exhaust pipe, let it hang down and heat the tip with a propane torch(NOT MAPP gas or oxy-acetylene), until red-hot and the flame from the torch blows red behind the sensor. Let it cool a bit, then torch it again from a different angle until all carbon/etc deposits are cooked off. This really works and can be used to eliminate buying a new $135 oxygen sensor. Other than that, your EGR valve may need cleaning.

NGK plugs work best. Platinum plugs don't help on this engine. I've tried them, other people have tried them, and the good old cheap NGK's work best.
