Hows the eBay o2 sensor holding

[@skylerwaite]

Bruh… a torque wrench is not a breaker bar 🤦🏻‍♂️

[@nateweiss7276]

Just got the same code . Did you get a rough idle before changing this ?

[@mrjones-pl5yr]

Why do you uncap the coolant reservoir?

[@alisahernandez1780]

I’m struggling to get the sensor unplugged from the metal bracket .. can you help out ?

[@Gannonvoegtline]

Sorry for the late response, my only tip would just be to trace the wire to the bracket from the o2 sensor and wiggle it out, it was really time consuming for me to get it as well.

Did you have heavy fuel consumption before changing it out ?

[@Gannonvoegtline]

I did not.

[@DanaRushford]

What was the link for the sensor ?

[@Gannonvoegtline]

It was just a random eBay sensor.
