well there catalog has the wrong numbers because from the start page if you look up the one part number 9193533 it is not a valid number then the other number 93171760 comes up also as a computer control sensor. if you read the disclaimer it even tells you that they can not promise their part numbers are right. so the best thing to do is call your dealer and get the most current part number then search for it right from the main page on their site because they change part numbers every so often don't ask me why. but they do. so you can verify my claim by calling your gm dealer and the part number is 90528435 is for the 99-01 catera I don't know about the 97-98 but it will save you a bunch of money.
