The original downstream O2 (after the cat) sensor was broken off by ice. Since then I have put 3 Canadian Tire downstream O2 sensors in about 3 months apart and I just replaced my first Mopar downstream O2 sensor. Why do they keep going bad. My second Canadian Tire O2 sensor left my stranded by causing the engine to flood, every time I hit the gas it was like hitting the brake instead. Once the car cooled down it would temporarly work. My Mopar O2 sensor just left me stranded by doing the same thing. The only difference this time is that the engine light never came on. I just replaced it with a new Mopar O2 sensor under warrenty but now the engine light comes on for a few short trips and then shuts off for a few short trips and then repeats. I have a hole in the top of my gas tank and a bad rear main seal if this matters. Why does this continue to happen? What is causing th O2 sensors to go bad? Is it something else? Anyone had this problem? Anything helps! Thanks.
