What grade of gasoline are you using, regular unlead or premium. You should be running at 3.5L or 3.8L V6 so premium gas should settle a ticking or knocking sound. Also, using a good gas additive can help as well.
Is there enough oil in the engine? If the oil is not low, you probably have a problem with your valves, in which case a trip to the mechanic is in order.
