Lots of ??? Please help me!

Ok so I just installed HF cats on top of my Cat back exhaust (all solo). I was first running the p0137 code only stating it was to lean bank 2. Well I solved that problem. The 02 extenders for the HF cats were impropperly installed (spell check). Anyway I reset the CEL and everything was fine.

Now I'm running codes P0137 Bank 1 Sensor 2 and P0157 Bank 2 sensor 2.

Is this related to just ONE O2 sensor? If so which one? Also could it be a faulty sensor or seomthing else?

I've noticed that my gear ratio is all off and when I'm barely pushing the gas I'm up to like 2500+ RPM! I had a tune prior to the install could that be the issue? Or could this whole code/rpm thing be related to a leak of some sorts?

Or could the code and rpm issue's be completely unrelated....

Sorry this is a lot of questions but I'm at my wits end with this.

PLEASE HELP!

I'm posting this in PCM thread as well to get more feedback so don't be offended for double posting please!

Perhaps give him a call up and talk it through with him; he may be able to give you some things to try or recommendations for next steps to try.

In any event, I replied to your first post on the other new thread, I would not recommend driving the car until your tuner can find time to take a look at some datalogging. I know the name brand tune places don't seem to take that long to fix a potential tune issue when a new mod is introduced...
