Engine dies out when oil cap is pulled off ++

my old K8 with crappy compression always died as well, my new (40,000mile?) ZE dies as well - I agree with Ian it's too much air gets in to the intake manifold making air/fuel ration too lean therefore stalls.

Unplug your PCV valve from the cover and see if you can feel a vacuum with your finger at the end of the valve. If you can't the valve is blocked.

Guys if you take off you air filter, and u push the thingy on your Mass Air Flow Sensor, the car is gonna die out. Meaning that more air than suppose to is going in.
So there is no phylosophy to this, when you take the cap off, engine dies out, now that is a simple concept, because more air goes in the engine.
