I own one, you can adjust it. There are two adjustment screws, one for each jet, but they are hidden behind a seal, you have to drill through a plastic like cap that cover the adjustment screws, email me for more specific details.

How do you install the throttle position sensor on a 83' caprice?

Assuming you have a 305 V8 with a Rochester Quadrajet carb. You will have to pull the carb, and tear it apart. The TPS sits in a groove in the front of the carb body. Buy a carb rebuild kit, watch the Youtube videos on rebuilding quadrajets, and do it. I just rebuilt my carb over the weekend. My 83 Caprice now runs great.
