A bad TPS can cause this, as can pretty much anything in the vehicle that controls idle (IAC, MAP, TPS).

No idea on the price, Victoria. I would have a shop diagnose it for you and then search online and do the repair yourself. A tech is generally only paid 0.3 of an hour to diagnose something like this so you shouldnt pay much more than $40.
