P2096 code

[Dxersquest]

Hi,

I just changed my catalytic converters and downstream o2 sensor, and now the truck is throwing me a p2096 code. Bank 1 fuel trim too lean. Any help would be great.
Thank you

Any exhaust leaks upstream of the CC? Any leaks can draw in air.

That's what I'm thinking. Having had a chance to test it yet. Thanks for you reply
