It may not have had anything at all to do with it. I have always changed the O2 sensors around 80k miles. I did not have an analysis performed on the sensor and the actual code indicated there was a problem with the O2 senser heater circuit. I will never know. The can did say that it was safe for O2 sensors for ALL cars. I will repost again when I run another can through at 160k miles (right before I replace the sensor again).
