Other stock people having this problem, maybe it truly is a vacuum leak for them. Sure, try wrapping the PCV fitting in teflon tape. Can't hurt. Reinstall it. Make 110% sure the couplers aren't kinked or bent over on the underside of the connections where you can't see. Etc...
Thats how vacuum leaks work, the larger the leak the worse the hesitation. Take my Jeep as an example, it has a hole in a 3/32" vacuum line and if you slam the throttle to the throttle to the floor (when the engine is still cold) it will stall. My point is that it doesn't take much to cause the problems that the 3 people are describing, heck a loose clamp could cause that.

In my oppinion this is an installation issue not a product issue.
