Was getting codes p0138 and p0139. Replaced the 2 rear o2 sensors on Friday, was not fun! Drove about 20 miles since then and the cel just came on with code p0161. Not a good fathers day and we are taking this car on vacation next week. Does this mean another o2 sensor is bad, or is one of the ones I bought bad? Used ngt o2 sensors.

Did a search and really didn't come up with much.

Thanks

I may have found the issue. When I connected the o2 sensors the clips did not lock. Looked like one came off some. Connected them so they lock this time. Will put 60 mikes on it tomorrow.
