Oldsmobile/Buick Repair: 96 olds ciera sl skipping?, olds cutlass, ac delco

Question
i have an olds cutlass that seems to be skipping or missing between 50 to 60 mph, mostly when at a constant speed. it comes and goes from time to time. i have been thinking tps but i just don't know it's almost as if it has a bad plug but replaced plugs and wires and still does it. any help would be much appreciated. it has 162,000 miles if that helps.it has a 3.1 v 6 engine if that helps.

       thanks much, harry mason
