2005 escape code po446

Please help!!! Posted earlier with my escape randomly stalling at idle. Getting a code po446 along with po511. Only stalls at idle after warming up and letting it set a while. When you go to recrank it that is when it won't idle or if it does its at 500 rpms or less. Also after driving it today it smells like rotten eggs. Replaced the idle control valve with no luck. What could cause this? Thanks

Rotten egg smell, from my experience, is usually cat-convertor.

Have you looked up the codes to see what they point to?

Yes. The code po446 says canister vent valve circuit and po511 says idle control valve circuit.
