Even since I re-installed my cats. I have been getting the over rich codes.

My LTFT's on bank 1 with shoot up well over +20 if I give it some gas. Then go down to normal.

I swapped O2 sensors, even disconnected it on the driver side.

And it still shoots up.

Any ideas??

what about at steady throttle? when was the last tune put in the car?

Cruising, Bank 1 stays above 0. Right around 3-7. Eventually it will drop below 0, like bank 2.

I think it started after I uploaded a tune. Not really sure, that was about the time my tranny started to slip.

I have thrown p0172's and p0175's

after my new tunes are put in the computer my STFT's go to crazy numbers. give it some time and see how it is. as long as your part throttle is ok and at 0 i wouldnt be too worried for the time being, drive the car some more and see if it changes

The tune I uploaded was for Transmission shifts. I took care of my LTFT's a while back.

I guess re-installing the cats could get things out of whack. I put them back in Sun.

It's just weird because they are only happening on one-side.
Even when Bank 1 finally drops below 0, just a touch of the throttle and they will jump up way past zero.

Cool, thanks.

watch which cells are showing rich. you may need to give some tuning attention to those particular cells.
