Clean the carbon out of the intake, and the EGR ports, use some carb cleaner and gently use a coat hanger for the smaller hole, toothbrush for the rest. They are probably clogged. Take the EGR valve back off to do this and the air tube off of the throttlebody, you can open the butterfly by hand and clean that too while you are in there.

i work at GM and we replace the vent vavles alot,along with evap canister and filter. but mostly due to dirt and mud sucking up into the filter .the filter is located left side of transmission by cross member,unless its been relocated already.evap canister is located at the front of gas tank or rear of it ,vent vavle is close to it .it is connected to evap canister with a tube or pipe witch ever you would like to call it. check evap for dirt or dust could be clogged.

You are right. You need the vent valve not the purge valve. The vent valve is a dealer item. Also this is a common problem and GM has released a bulletin on this that involves moving the location of the valve and running some new lines. It comes as a kit from GM, and it costs about a 100 bucks.
