It began to happen a couple of days ago, As soon as I let of the throttle the RPM needle gets stuck and my idle is high. One time the car even backfired really loud as soon as I shut it off. So what I do is turn the car off and then turn it back on so the idle is back to normal. What could be wrong?

id run codes, but at first blush, sounds kinda like a vac leak. that can cause hanging idle and backfiring.
good luck.

See http://www.members.tripod.com/sparkplugs/idle.htm or http://www.mightyap.com/index.htm for some help on your surging idle.

Both sites point to bad TPS sensors as being the culprit in the surging idle that goes high and sticks until you shut off the engine.
