Update II: Fark, it still keeps doing it now and again on extended cruises. Should I look into new o2 sensors? I've run fuel injector cleaner and after conferring with a few buddies, they state that they have had fuel injector cleaner ruin their o2 sensors. All of the wires are now secure and connected so it is either replace the sensors or run new wires to wherever they go (or both ). Daggone 13 year old cars.
