Could be a faulty idle control valve (disconnect it and if the problem of the revs hunting is still there then you can rule it out), lambda sensor or air leak on the inlet (can't imagine that there is s a sensor for this unless the inlet manifold pressure shows a problem) . The best bet in my opinion is to take it to Fiat garage and get them to read the fault code from the ECU - might cost 40 but it will save an awful lot of time and money if you start replacing the wrong parts.

Its definitely the idling actuator (aka idle control valve). Mine did exactly same thing last month!! Cost around 149 plus VAT but you can easily fit it yourself in 10 mins.
