Clogged Catalytic Converter

if the nuts were old and rusty on the O2 sensor studs just ahead of the cat, would a plugged/clogged cat "blow them off?"

Happened just after I got my 94 4Runner up and running. Put new nuts on, it's fine. Getting horrible gas mileage on the highway, 10MPG, also can smell something like propane turning off the truck and getting out.

Are these symptoms the cat needs replacement?
