Orville Redenbacher in my L28 - Please help

So last night I went out to Seafoam my 280zx and when I pulled the PCV hose to the brake booster off, the engine died.

I plugged the hose with my thumb and started it back up, went to add seafoam and it died before I could. I decided to see if I could get it to stay running by holding down the throttle a bit, which worked. I let go and the engine died. I only have so many hands, so I put the Seafoam away and made a video to get some feedback

1. ) checked the distributer cap for cracks, it looks ok.

2.) I replaced the plugs and wires a week or two ago.

3.) I siphoned out 10 gallons of old gas and replaced it with fresh 91 octane gasoline.

I have a new fuel filter I'm going to put in today. I don't have a compression tester, fuel pressure tester so I don't know what the numbers are.

In the video, the PCV hose is removed, and I'm keeping the engine running by playing with the throttle. When the hose is connected, it pops less frequently in the intake manifold. My dad is lazy and says "Just take it to a mechanic and throw money at it" but where's the fun in that?

I'd like to fix it myself, or at least know if this is beyond a weekend of work. Thanks for your input

You have a huge vacuum leak, get that hose back on and make sure there is no leaks

This is my suggestion after reading your post, i don't even want to bother looking at your video so i might be wrong

[Dobber]

The guy goes to the trouble of including a video for diagnostic purposes and you can't be bothered to look before you post your diagnosis. ???????

[ChrisZ]

Nope.

That's Chris's prerogative. Could be vacuum, could be fuel supply. The video really doesn't help (IMO) w/o knowing the fuel pressure/compression, etc.

Thanks Stepen for backing me up, Dobber, you should spend your time on reading what the OP write, i belive he have his own answer
