Review on 🔥 ECCPP Oxygen Sensor 234-4018 234-4012: Perfect Fit for Chevrolet/GMC 4.3L 4.8L 5.7L Models 96-02 - Heated O2 Sensor Upstream Downstream 4PCS by Sean Franklin

I bought them in November 2018 and installed them the weekend after they arrived. You should solve my problem. I went from one bad code to ALL 4 bad readings. Not only did I not save any money with the purchase, I was so confident that "new" means "new" that I bought a car computer in July 2019 and took it to a mechanic. I invested over $500, I didn't have to invest in this machine because I bought non-working, brand new O2 sensors from this seller. I don't want my money back. I would like Revain to read other 1 star reviews in the last 9 months and remove this seller from the market. This is my Christmas wish in July.
