Default 93 LS Check Engine Light

93 LS Runs fine until Ck Engine Lt comes on and then runs rough.
When on the scanner, all shows good and then when engine light comes on message that there is no communication comes through. First guess is that "something is loose" but no luck yet in finding it.
Any other thoughts?
