i have a fiat brava 2000, just the day before yesterday i turned engine on and it started revving on its own in idle. i tried disconnecting the battery and reconnecting and it didnt help. what could be the problem and how much should i expect to pay to get it fixed?

sounds like the idle control valve/stepper motor which is located on throttle body, the're cheap to replace
