Which explorer engine?
Short answer...Yes
Long answer- those older engines use older emissions systems, So not only would you have to make it work (most likely using a harness from the 92), but you would have to try and get it to pass emissions wherever you are from.... and it may NOT pass visual inspection even if you don't have a smog test.
Because everything on the 01 is computer controlled in some way/shape/form it would probably be more trouble than it is worth.
