I believe I need to replace these O2 sensors.
Can anyone confirm my diagnosis? I've attached the error codes I'm getting. SES light is on. No limp mode but car is not smooth going up through the revs and doesn't feel like I have full power.
Also I suspect this is why I can't seem to break 11.3 MPG? (My right foot I'm sure has something to do with that but this seems awfully low?)
I was going to get the Bosch ones:
Amazon.com: Bosch 17051 Oxygen Sensor, OE Type Fitment: Automotive
And this tool to do it:
3/8" Offset Oxygen Sensor Wrench
Debating if replacing bolts is really necessary also?
