so after you removed the sensor was the sensor metal reacting with the intake manifold ?

J Cat, I did post a picture of the bad one, after I removed it. In the last picture I added, you can see the screw head on the top of the sensor body. You can also see the threads of the stud, and there was no visible corrosion. But there was a dark substance between the threads, and the tapped hole had some in it's threads. Maybe it was some type of corrosion, I thought perhaps it was from the poor plating that they coated that Autozone unit with.
