O2 sensor is a possibility...Oldsmobile block i.d. numbers?
However when you say that at warm-up the idle will vary around 2000 or 1500 are you saying the idle jumps up and down? or that it slowly drops from 2000 to 1500? If there is a variation, meaning it jumps back and forth between 1500 and 2000, it's more likely you've got a leak in the intake system some where. Either in the manifold or gasket.

If it's holding idle stead, then that's fine. I would advise cleaning out the carburator first. Make sure your choke plate is clean and moving freely.
