I doubt it would have much of an effect on your gas mileage. Does it warm up on the gauge? Yes, the gauge warms up fine. It's just RPM is high, around 900, and I can feel the vibration. The dealership said it is whin the spec. But it wasn't like this before. jw

Ok, all I have read so far is that the idling low and rough. I have a 2001 RX300. The idling has been high and rough. It seems the car never warms up. The gpm has been poor. Could this be the same problen with a dirty IACV? jw
