Hmmm are you sure it's the IACV? My car cold idled at 1700 yesterday briefly but I think it's because I did a bad splice on an O2 sensor heater circuit wire and the ECU is having the engine idle high in case there was a more serious driveability issue. At any rate, 1700, 1500 not a big difference I imagine, it's probably just a few hundredths of a gallon per hour more.
