I have 98 explorer im getting same codes ive worked on cars all my life I havent replaced anything but my fuel filter so far on the explorer and that wasnt it.I know people tell you to replace all that other stuff,but if you know cars and how the stuff works thats on a car then you can fix anything with out people telling you;you need to buy this and then this and there just fishing when the dont know there as* and whole in the ground.Im going to replace my lower and upper intake seals like he says above.At least theres one more smart one out there and not someone that thinks they know it all like people that work in the parts places and some dealers.

Asked several co-workers who also work on vehicles and they suggested the O2 sensor preceding the catalytic converter or possibly the port vacuum switch. My father and I cleaned the ports leading to the port vacuum switch with carb cleaner and it helped a little bit, thus far have not had rough idling again yet
