Will not stay running, vacuum line diagram needed

Can't figure out correct way to read the vacuum diagrams. I know for sure that the car will shut off upon starting unless you keep a heavy foot on the gas. If not, it shuts down as quickly as it started up. Also, although it ends the same way, it does run a little better when the MAF sensor is unplugged (yes, will be replacing).

My question is, what am I missing when checking these vacuum lines? I struggle with not having any braking strength, pretty much. You have up pretty much stomp your foot as hard as you can from way back to even make sure you can stop at all. And if you take your foot off the gas at all, or don't do the "red light= neutral and gas pedal maneuver", it's done.

Someone mentioned checking out the PCV valve. I just want to be and to start the car without having to keep a steady flow on the gas just to keep it running in park or drive. And to be able to use my brakes as needed without feeling like I'm trying to put my foot through the floorboard.

Any thoughts or opinions on the vacuum lines, non-existent brakes, immediate cuts off at start and in drive and neutral, and what about the PCV valve?

Thanks for all of your help!
