Check engine came on and read 02 sensor bank 2. I just replaced all 4 30days ago so I doubt its dead already. What can be causing o2s(Rears) to keep going out? Ive heard everything bad Cats...Egr...bad gas....
I replace my tr55ix with tr6 gapped .048 could this have done it? (Engine light came on 36 hours after install
Im also guily of not always using 93gas (89midgrade)

Just need :help: tracing problem. ....
Car gets hot inside and gas mileage is down

Not likely your problem but the gap ought to be .045.

Have you actually data logged and tested the o2's or are you just replacing them when you get a CEL?

So if I'm understanding you, your code is showing bank 2 sensor 2?

You could always thermo heat test both cats and see if one is significantly higher than the other.

Where did you get the O2 sensors, I've had lot of trouble with anything other than motorcraft and denso(oem supplier).

I had Bosch 02 sensors in my car from AutoZone, they lasted about 10 miles before I took them out and I bought Motorcraft ones
