I was about to suggest this, when my brother decided it would be a good idea to redline and kill the ign it did the same thing, full throttle and vroom.
Its called an IAC motor, it stands for Idle Air Control. It is what your problem is sounds like yours has failed. They are not cheap probably closer to 78-80 bucks from advanced auto. I would recommend getting the one at napa for 8 bucks more.

Ok the Idle Air Control Valve lets air into your engine when your throttle body is closed. If it won't start with your foot on the gas pedal you probably have a different problem. Did you ever check to see if you are getting spark?

Also be sure to prime the carburetor and give it a few pumps. Lol im just messing with you but if your having all these problems and if your IAC is working properly then id check your cps, its a royal pain to get to but its a common thing that goes on xj's.
