These cars are like clockwork...they are so maintenance pretictable. Just like the saying "lights, (followed by) camera, (followed by) action!" Pretty much...if the temperature dial is out on my '91 8-fiddy, chances are if you have a '91, yours will likely be out too. If your Air Intake Manifold goes, then well...hmmm...lets just hope I'm not always right...this could get expensive (lol).
