i have a 97 chevy blazer and it has a 4.3 vortec engine and i was wondering how to change the sensor . i know it is located on driver side behind the cadalac converter and i need to know if i can change it and how hard is it.
Go to www. autozone.com. When you're there click shopping and then choose your vehicle and year. Find your sensor and scroll to the bottom of the page. There will be a link that tells you how to replace. Print it and there you go. Good Luck!
