Autozone says the code says bad IAT sensor. Gices them a part no. which they sell me.

WHERE does it go?

found some stuff online that says it's integrated into the MAF sensor.
Then WHY did it come up with a part for it that wasn't the MAF?

Help me please

 

the IAT is usually located on the intake manifold in the air channel somewhere. sometimes it's located near the MAF sensor. I can also be called an air charge sensor. On your car, it may well be the MAF though. Hopefully someone who knows more about the sable will chime in.
