Hope everyone is fine. I need a little piece of advice. @rajaatta
Recently I have visited a mechanic for routine maintenance. So I asked him to check the Cat converter. He mentioned "Opening Oxygen sensor and put it back will give check engine light and to remove that light we may need to replace the sensor."
How true is that? just opening a sensor and put it back will give engine light seriously!**
Cleaning Cat converter via the Carbon clean method is good or not?** Is it really efficient method?
Any help would be appreciated
