Good afternoon,
The 446 code is for the evap system. It has no direct influence on the rich running.
I attached a flow chart for the 446 for you. The canister vent solenoid is the most common failure for this.
As far as the stalling, Have you tried cleaning the throttle body? That is a very common issue.

I attached the test for this code. You more than likely have an issue with the purge valve. If you do then you need to make sure the charcoal canister does not have fuel in it. If it does then the charcoal breaks down and get in the valve.
Run through this test and tell us what you find. Thanks
