So I am almost finished cataloging for my custom flex fuel tune and ever since I E fuel in my car I get this code here
118001 - Mixture control: Fuel-air mixture too lean.

And not very often but I also get

190F08 - Fuel tank ventilation system: Malfunction.

Could one part in particular cause both of these codes? I am at a loss. Or is it the cat reacting badly to the E. Any advice would be greatly appreciated!

Attached is a link to a recent log, I’m not technical so if anyone notices what might be wrong that would be great
