I just noticed in one of my earlier posts, I typed smells and not smalls. It was an autocorrect. I'm very curious on how they setup one cat versus two smalls. Do they tap both post cat o2 sensors into the one pipe after the new single cat? Not sure if that would mess up any readings as both precat o2s would have diff readings for each bank but then see the same post cat results.
I get the rotten egg smell from time to time. I get odd shifting driving around town, already changed tps, drained transmission, drained front and rear differentials. I also noticed on my scans that bank twos post cat o2 starts running and staying at a high voltage after idle whereas bank one returns to low voltage if it does happen to creep up. Through some reading that leads me to think the bank 2 cat is clogged. But, I'd hate to spend the money if its not it. I've already thrown enough hundred dollar bill guesses at it. Lol. Thanks for the update.
