i have blown the front o2 sensor on my car twice now.
The first time was due to an safc2. The dealership replaced the front 02 sensor for $140 for the part 60 for labor.
The second time i decided i didnt want to spend that much so i purchased the part myself, from a different dealership. It cost me $70. and i installed it myself. This was less than 2000 miles ago.
lately the car is acting up again. stuttering, and feeling down on power. I brought it to the dealership and they claim that the front 02 sensor is shot again. Is it possible that i was sold the incorrect sensor? im thinking maybe i was incorrectly sold the rear sensor and i installed it where the front would go. is this even possible? would it fit? what would explain the price difference in the sensors from one dealership to another if i was getting the exact same oem part?
