I changed the intake of my 83 cutlass supreme a few years ago and I had to switch a 2 barrel carbareator into a 4 barrel. I turned off the map sensor and computer devices. I now want to go back to the original motor. What do I have to do to get it back to original shape? ---

Can’t you just reverse the procedure. ---

If you didn’t keep those parts, you will have to buy them to reverse the procedure as @Purebred said. If you need to buy those parts, good luck finding anything for this 35 year old car. Why would you WANT to change back, just for curiosity’s sake?
