Yup very normal, you are introducing a massive leak, and the computer needs to know how much air goes into the engine. By doing that, you allow a lot of air to bypass the MAF sensor, and the mixture goes way lean, engine stalls.

1, why are you pulling the pcv when the car is running? 2, 1 does it because the pcv works, the other doesnt do it because the pcv is faulty...this forum makes me want to shoot myself lol!
