I watch your videos everyday 😊. Seems the more professional mechanic looks the less they know. I have a 2012 Mitsubishi outlander sport 133,000 miles. I can't get rid of the PO420 code low efficiency bank 1 car runs rich exhaust smells like fuel comes in the cabin. I replaced the O2 sensors with Denzo and replaced the catalytic converter with an OEM. New computer, pin test wire harness, new spark plugs, serviced the fuel injectors and pressure tested the exhaust and resonator. Mechanics seem to just want to throw parts at my car and are now saying I need Mitsubishi issued O2 sensors they are $1,500 what do you think?

- What are the g/s that the MAF sensor is showing at idle?
- Has anyone checked to see if the Purge Valve is leaking?
- Lastly, If you unplug the upstream O2 sensor and force it to stay in Open Loop does it still smell like fuel?
