One thing I noticed though is that if the air hasn't been purged from the coolant system the temp sensor is high and dry and the car stays on high idle. There is a bolt screwed into the top of the engine, in front of the throttle body, by the thermostat. Loosen it with the radiator cap off and the heater set to max heat, and air will vent out of the bolt hole. When coolant starts to come out tighten it. Take it for a ride and see if the engine idles down.
