I got a 2nd gen mazda 6, 2.5L. I keep getting a lean code and if I clear it sometimes it will come back as a rich code. To me it seems like the o2 sensors aren't working efficiently and the mixture is fluctuating up and down trying to regulate. The only thing that confuses me is there's no code for an o2 sensor circuit or cat efficiency. I would like a 2nd opinion if anyone has any input I would appreciate it.

Awesome content! I'm great a changing parts but know nothing about using scopes and multimeters in car even though I have a low voltage background. I definitely learned a lot from this video. Can I buy you guys a beer or something?

No misfire codes (P0300 - P0308) for a bad O2 sensor?
