Q: How long does a new 02 sensor need to be in the car before it will fix the problem?
We're having a misfire on the 6th cylinder. We just replaced the o2 sensor this morning (because besides the catalytic converter, we've replaced or checked everything that could possibly be causing the misfire). How long do I need to drive with the new o2 before it will fix the problem? Or would the problem be fixed immediately as soon the sensor is replaced? Does this mean I need to start considering changing the catalytic converter?
