I'm not getting any of the cat efficiency code(s). Steve99 was saying it may be a leak at the o2 sensor since one of the bung didn't snug in at first. They forced the o2 sensors in one of the bungs. So now that leads me to think that where the problem lies. Leak where the o2 sensor is. Question is, I don't know which o2 sensor.
How would I know if that is where the actual leak is?
And how would I be able to fix this?
