So I was on my way to school a little while ago, hit an open stretch of beltway 8 and gave her the beans. After I was done and was slowing down I look at my gauge cluster and see a CEL. So I get to school, get a scan tool and see the P2096 Post Catalyst fuel trim system too lean bank 1. I cleared it and walked back to class. My question is what would have cause this? I searched and didn't find any information pertaining to my set up and this problem.

All's I have on the car is TBE with UR high flow cat, SRI, HKS bov (in conjunction with the stock bov), and wastegate actuator.
I just put a breather on the PCV side and capped the other nipple on my SRI.

Im thinking bad 02? Ill let you guys know if the code come back.
Thanks

Strange you got it with a hf cat, pretty sure that's the code guys with no cats get. Bad 02 or loose plug maybe...

Ill check the connectors and the last 02 sensor. Looks like its time for a wideband:fleshbox:. When I had the CEL the car was hitting full boost fine and didnt drive any differently so should I be more concerned than I am?

I get it all the time. I also have a full TBE system with high flow cat. Car drives no differently. Sometimes it clears itself.

I'm at like 15K miles with full tbe and hf cat, never had a 2096 cel.

Sometimes those "high flow cats" can flow a little too much....Confuses the ECU and it assumes the cat isn't there.

That was the explanation I was looking for. Thanks Tim!
