99 Cherokee's don't have carburetors...they have throttle bodies since its fuel injected.

I would perform the following in order:
  1. Clean your throttle body and remove any carbon build up. Its recommended to remove the IAC and other items and clean thoroughly.
  2. Check the IAC (Idle Air Control circuit) to make sure it is working correctly. If its bad or dirty, it will cause the engine to stall at idle.
  3. Check for ant intake manifold vacuum leaks. When you mentioned that it sounds like its sucking lots of air, chances are a vacuum hose came off
  4. Check your spark plugs.
  5. Your coil could be going bad.

Have you checked that the airfilter isn't blocked or damp? What about water in the carb?
