Pull off the housing around your column and visually inspect the shift tube. Sounds very familiar to me and the cause of my woes was a broken shift tube. This is the exterior shaft tube that runs down the column from the shifter to the shifter cable.
This occured on a 94 for me, but the shifter handles are the same, so I'm guessing the tube assembly is also the same one. I had a spare in a parts truck and swapped it out in about an hour...and that included a couple of wobbly pops.
