On a properly functioning fuel injected L28, it's supposed to die when you remove the oil cap. I just read a post that said if your fuel-injectd car doesn't die when you remove oil cap, you have major vacuum leaks. I went out and tried it and whoo-hoo! mine died.
Is this normal?
The vacuum through the PCV system on my '77 280z seems to be extremely high. So high in fact that my engine will die if I take the oil cap off while the engine is idling. Is there an adjustment for this? What about the air regulator valve? Is there something that I am missing? The PCV valve is working properly, and I think the vacuum lines are hooked up correctly. Can somebody shed some light on this for me? Thank you

Yes it should die, but if it doesn't die, that doesn't mean it has to have a vac leak, it can just be just adjusted too rich.
