IAT sensor madness

I set my Scanguage II to give a readout of the intake air temperature. The given temps are all over the place.

Today at a steady 60 mph, the temps were ranging wildly from 58 to 89 with the outside temp being 53. I had pretty wild changes when I had a cold air intake on it as well. When I start it, the temp starts out around 90 wether the engine is hot or cold.

Is so much flux normal or should I be replacing the sensor? I know that depending on make, cold air or warm air may affect performance and/or FE.
