This has been a common issue for years now but I just had one in the other day as they seem to be acting up again with the cold winter this year. While it is only 2 screws Ford went and locked them in there good with too much Loctite. So if you find yourself replacing one please watch my video on how to remove it so you don't snap off the screw in there then it gets ugly from there. This applies to any engine or model that has this type of replaceable sensor on it with the early Ford Electronic Throttle Body systems.
